Diablo Motors, dealer #XXXXX, has been in San Ramon for 21 years. The complaint involves a customer having a dispute with a different company in Antioch, and involves a 2001 Mitsubishi, which we did not sell. We sell BMW and Mercedes here. I know there are many companies with the word "Diablo" in the name. Please see to it that this dispute is removed from my record, and attached to the proper company.
