Technicians at Dave's Automotive were able to fix an intermittant problem that the GM Dealer's shop could not!! I was referred by a friend at work and was very skeptical...but Dave's techs repaired it for a song. Also available are computer diagnostics, tune-ups, scheduled maintenance, lube & oil, air conditioning, even tranny and engine rebuilds. Prices are VERY reasonable and the staff quite friendly and respectful. Will return!
