“I mostly own classic cars because vehicles nowadays are just computers on wheels, so it's hard to find mechanics who work on cars older than the 1990's. I sent my '64 GMC pickup to Dettmer to figure out what was wrong, and within 2 weeks it was fixed and running perfect. Since then I've sent all my classic cars to them with perfect results. It's hard to find a trustworthy shop you don't have to worry about — they take pride in the work they do.”
