File No. 001-33861

Dear Ms. Gilmore and Mr. James:

On behalf of Motorcar Parts of America, Inc. (the “Company”), we are submitting this letter in response to comments received from the staff (the “Staff”) of the Division of Corporation Finance of the Securities and Exchange Commission (the “Commission”) contained in its letter, dated February 5, 2020, relating to the Company’s Form 10-K for the Fiscal Year Ended March 31, 2019 (the “Form 10-K”), Form 10-Q for the Period Ended September 30, 2019 (the “Form 10-Q”) and Form 8-K filed November 12, 2019 (the “Form 8-K”).

The Company has carefully considered the Commission’s guidance, and, for ease of review, we have set forth below the numbered comments of your letter in bold type followed by the Company’s response thereto.

Comments:

Form 10-K for the Fiscal Year Ended March 31, 2019

Management's Annual Report on Internal Control over Financial Reporting, page 39

We note that your assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of D&V Electronics which was acquired in July 2017. Tell us how you considered the guidance in Question 3 of the SEC's Frequently Asked Questions on Management's Report on Internal Control Over Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports in concluding it was appropriate to omit an assessment of D&V Electronics. That guidance indicates that “the period in which management may omit an assessment of an acquired business' internal control over financial reporting from its assessment of the registrant's internal control may not extend beyond one year from the date of acquisition, nor may such assessment be omitted from more than one annual management report on internal control over financial reporting.”

Response:

As explained in Item 7, Business Acquisitions Section, we acquired Mechanical Power Conversion, LLC on December 21, 2018, which operates using the DBA of D&V Electronics USA.

As we stated in Item 9A, Management’s Annual Report on Internal Control Over Financial Reporting, we excluded D&V Electronics USA due to the timing of the acquisition being within the fiscal year ended March 31, 2019:

Management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of recently acquired D&V Electronics USA and Dixie Electric, Ltd, which are included in the 2019 consolidated financial statements of the Company and constituted 2% and 2% of total and net assets, respectively, as of March 31, 2019, and 1% and 10% of revenues and net loss, respectively, for the year then ended.

The entity we acquired in July 2017 was D&V Electronics based in Canada. This entity is included in our internal controls report for the fiscal year ended March 31, 2019. Both D&V Electronics and D&V Electronics USA will be included in our internal controls report for the year ended March 31, 2020.

Similarly, please explain to us how your auditors considered the guidance in Question 3 of the SEC's Frequently Asked Questions on Management's Report on Internal Control Over Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports in concluding not to include an evaluation of the internal control over financial reporting of D&V Electronics in their audit.

Response:

As discussed under the response to Question #1, the exclusion of D&V Electronics USA was permissible under the guidance in Question 3 of the SEC's Frequently Asked Questions on Management's Report on Internal Control Over Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports as the acquisition was within one year of March 31, 2019.

Please revise your disclosure relating to the U.S. Customs and Border Protection claim in future filings to also clearly disclose (i) the nature of any accrual you recorded, and (ii) an estimate of the reasonably possible loss or range of loss in addition to any amounts accrued or a statement that such an estimate cannot be made. Refer to ASC 450-20-50.

Response:

We determined as of September 30, 2019 a reasonable estimate of loss relating to the U.S. Customs and Border Protection (“CBP”) claim and accrued that amount as a loss contingency, as it is estimable and probable. We have determined, and respectfully request that the Staff consider, that (1) the amount is not material to our financial statements or investors and (2) the disclosure of such an amount would put us at a disadvantage in our negotiation with the CBP and therefore that such disclosure is not necessary. The Company will continue to consider the requirements of ASC 450-20-50 to ensure appropriate disclosure of its accruals.

Form 8-K filed November 12, 2019

Exhibit 99.1

You present non-GAAP measures for adjusted net sales, adjusted net income, adjusted gross profit and adjusted EBITDA that reflect adjustments for return and stock adjustment accruals as well as customer allowances related to new business, the impact of sales price increases related to tariffs, the core sales and cost (recovery) related to a cancelled contract, and new product line costs. Your non-GAAP measures appear to substitute individually tailored recognition and measurement methods for those of GAAP. Please tell us how you considered the guidance in Question 100.04 of the Compliance and Disclosure Interpretation on non-GAAP measures in concluding that each adjustment was appropriate.

Response:

The Company presents adjustments to our GAAP measures and the disclosure related to them in response to questions previously asked by investors, and solely to provide additional information to them to help understand the Company’s business and results of operations. The Company does not intend to, and does not, substitute individually tailored recognition and measurement methods for those of GAAP and does not disclose that it is doing so. Rather it is providing additional disclosure about the impact of various matters on our business. The Company advises the Staff that it has carefully considered the guidance in Question 100.04 of the Compliance and Disclosure Interpretation on non-GAAP measures (the “CD&I”) and concluded that each adjustment is appropriate. In each case, Exhibit B describes the adjustment and why it is appropriate.

•

Return and stock adjustment accruals related to new business and product line expansion. Please reference Items 1a in the Press Release attached as Exhibit A, Item 1b in the Form 8-K attached as Exhibit B and Item 1c in the Form 10-Q attached as Exhibit C.

Revaluation – cores on customers shelves and inventory step-up amortization. Please reference Items 6a in the Press Release attached as Exhibit A, Item 6b in the Form 8-K attached as Exhibit B and Items 6c in the Form 10-Q attached as Exhibit C.

We note that you adjust several of your non-GAAP measures for “acquisition, financing, transition, severance, new business, earn-out accruals from acquisitions, restatement related fees and other costs.” In addition, these items appear to be recurring in nature since you reported similar costs in several comparable periods. Please address the following:

•

Describe to us each of the items and quantify each category of costs included in the adjustment.

•

Tell us how the amounts reflected in the adjustments reconcile to the amounts discussed in the MD&A of your Form 10-Q for the period ended September 30, 2019.

•

Tell us how you considered the guidance in Item 10(e) of Regulation S-K which prohibits adjusting a non-GAAP financial performance measure to eliminate or smooth items identified as unusual when the nature of the charge or gain is such that it is reasonably likely to recur within two years or there was a similar charge or gain within the prior two years. Otherwise, revise your presentations in future filings to comply.

Response:

Similar to the response to comment 4, the Company presents these adjustments and the disclosure related to them in response to questions by investors, and solely to provide additional information to them to help understand our business. Please reference Item 7a in the Press Release attached as Exhibit A and Item 7b in the Form 8-K attached as Exhibit B. The Company provides supplemental information on these adjustments and their location in the Form 10-Q in Exhibit D. Finally, the Company advises the Staff that it has carefully considered the guidance in Item 10(e) of Regulation S-K, including question 102.03 of the CD&I, and confirms that it does not identify any of these items as unusual or non-recurring.

Item 2.02. Results of Operations and Financial ConditionOn November 12, 2019, Motorcar Parts of America, Inc. (the “Company”) issued a press release announcing its earnings for the fiscal quarter ended September 30, 2019 which is being furnished as Exhibit 99.1. The information contained herein and in the accompanying exhibit shall not be incorporated by reference into any filing of the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference to such filing. The information in this report, including the exhibit hereto, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended.The attached exhibit includes non-GAAP Adjusted net sales, non-GAAP adjusted net income (loss), non-GAAP adjusted EBITDA, non-GAAP adjusted gross profit and non-GAAP adjusted gross margin. The Company believes that these supplemental non-GAAP financial measures, when presented together with the corresponding GAAP financial measures, provide useful information to investors and management regarding financial and business trends relating to its results of operations. However, non- GAAP financial measures have certain limitations in that they do not reflect all of the costs associated with the operations of the Company’s business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The Company makes adjustments to the following items to calculate its non-GAAP financial measures: Return and stock adjustment accruals related to new business and product line expansion. In connection with new business, the Company may establish return and stock adjustment accruals to account for the anticipated increased levels of business activity and product line expansion. The Company excluded these up-front accruals from net sales because they do not reflect the Company’s operations on an ongoing basis and excluding such accruals enables period-over-period comparability. 1b Customer allowances related to new business. In connection with new business, the Company may purchase coresfrom customers, may purchase the customer’s prior supplier’s inventory, or may provide certain customer allowances. The allowances are granted on a negotiated basis, and the Company excluded these allowances from net sales because they do not reflect ongoing product pricing or net sales and excluding such allowances enables period-over-period comparability. 2b Impact of sales price increases related to tariffs and Tariff costs paid for products sold before price increases wereeffective. The Company excluded the impact of sales price increases related to tariffs and tariff costs paid for products sold before price increases were effective because excluding such amounts enables period-over-period comparability. 3b Core sales and cost (recovery) in connection with a cancelled contract. The Company excluded the core sales and cost (recovery) in connection with a cancelled contract, because they do not reflect the Company’s operations on an ongoing basis and excluding such sales and costs enables period over-period comparability. 4b New product line start-up and ramp-up costs, and transition expenses. These are start-up costs incurred prior to recognizing sales for the launch of new product lines and costs of ramping up production. Transition expenses are costs incurred in connection with the expansion of the Company’s operations in Mexico. The Company excluded start-up and ramp-up costs, and transition expenses because they do not reflect the Company’s operations on an ongoing basis and excluding such costs enables period-over-period comparability. 5b Revaluation- cores on customers’ shelves and inventory step-up amortization. On a quarterly basis, the Companyrevalues cores on customers’ shelves, which are included as part of contract assets on the balance sheet. The revaluation is in accordance with the Company’s accounting policies on contract assets. The impact of this revaluation is reflected in cost of goods sold. The Company excluded the revaluation for cores on customers’ shelves because the core inventory on the customers’ shelves is not consumed or realized in cash during the Company’s normal operating cycle. Additionally, amortization of inventory step-up relates to an acquisition and is excluded because it is not ongoing. Neither is used by management to assess the profitability of its business operations. 6b

Cost of goods sold for cores recorded in connection with a cancelled contract. The Company excluded the cost of goods sold for cores recorded in connection with a cancelled contract because they do not reflect the Company’s operations on an ongoing basis and excluding such costs enables period-over-period comparability. Share-based compensation expenses. These expenses primarily consist of the cost to provide employee restricted stock and restricted stock units, and employee stock options. The Company excluded share-based compensation expense because it is not used by management to assess the profitability of its business operations.Mark-to-market losses (gains). The Company excluded mark-to-market gains and losses, including lease liability remeasurement, because they are unrealized and are not reflective of actual current cash flows and operating results.Write-off of debt issuance costs. The Company excludes the write-off of debt issuance costs because they are not related to the Company’s ongoing business operations or financing arrangements.Item 9.01. Financial Statements and Exhibits.The following exhibit is furnished with this Current Report pursuant to Item 2.02:(d) Exhibits Acquisition, financing, transition, severance, new business, earn - out accruals from acquisitions, restatement- related fees and other costs. The Company has incurred acquisition, financing, transition, severance, new business, earn - out accruals from acquisitions, restatement-related fees and other costs that are not related to current operations. The Company excluded these costs to enable period-over-period comparability. 7b Cost of customer allowances and stock adjustment accruals related to new business and product line expansion. As described above for the adjustments to net sales, the Company also adds back the cost of customer allowances related to inventory purchases and stock adjustment accruals to cost of goods sold because they do not reflect the Company’s operations on an ongoing basis and excluding such costs enables period-over-period comparability. 8b Exhibit No. Description 99.1 Press Release, dated November 12, 2019

Since this immaterial operating segment meets the aggregation criteria of ASC 280, we have combined our operating segments into one reportable segment.Results of Operations for the Three Months Ended September 30, 2019 and 2018The following discussion and analysis should be read together with the financial statements and notes thereto appearing elsewhere herein.The following summarizes certain key operating data:Three Months Ended September 30,2019 2018 Gross profit percentage 24.3% 20.1% 2019 2018 Net sales $ 150,374,000 $ 127,939,000 Cost of goods sold 113,801,000 102,228,000 Gross profit 36,573,000 25,711,000 Gross profit percentage 24.3% 20.1% (1) Annualized finished goods turnover for the fiscal quarter is calculated by multiplying cost of goods sold for the quarter by 4 and dividing the result by the average between beginning and ending finished goods inventory values, which includes all on-hand core inventory, for the fiscal quarter. We believe this provides a useful measure of our ability to turn our inventory into revenues.Net Sales and Gross ProfitThe following summarizes net sales and gross profit:Three Months Ended September 30, Net Sales. Our net sales for the three months ended September 30, 2019 increased by $22,435,000, or 17.5%, to $150,374,000 compared to net sales for the three months ended September 30, 2018 of $127,939,000, reflecting continued growth for our rotating electrical and wheel hub products.
