Motorcar Parts of America Inc., which rebuilds vehicle alternators and starters for cars and light trucks, said late Wednesday that it bought certain assets of a privately held competitor.

The Los Angeles company did not disclose terms of the deal, which was with owners of Reliance Automotive Inc., based in East Berlin, Conn.

Chief Executive Selwyn Joffe said the deal will give his company a major automotive retail customer, but did not name the company.

“We expect that this will be a basis for solid revenue growth,” Joffe said in a statement.

Shares on Thursday were up 8 cents, or 1.5 percent, to $5.09 in midday trading on the Nasdaq.
