ABC7 saw several surprised customers arrive at a closed dealership in Vallejo on Friday. One was left wondering how he would retrieve his car from the now shuttered repair shop while another got her car just in time.
"He told me he was calling me out of, it was a courtesy call, to let me know Momentum had been shut down," said Denise Claibourn of Vallejo, who quickly retrieved her car.
Fellow Vallejo resident Eugene Porterfield wasn't as lucky.
"It bothers me because there's no information or anything like that and now I got to get it from them," he said.
As of Friday, Porterfield said he has no idea how he will get his car back.
Two dealerships under the Momentum Auto Group remain open. They include Momentum Chevrolet in San Jose, which is under majority Chevrolet ownership, and Momentum Toyota in Fairfield.
A manager there declined to speak to us or explain the closures.
