We've taken a few cars there (our two current ones, plus an older car) and they are great. Attentive, reasonably priced and HONEST.
When I went to sell my Ford Minivan, there was some sort of a leak and a prospective buyer took it to a AAA recommended place who looked at it and told the buyer that the engine block was leaking and it would cost at least $800 to fix. Needless to say, they didn't buy the car. So, based on a craigslist recommendation, I took it to Don's to get it fixed (and to get a second opinion).
I was pretty happy when they called back to say that it was a hose leaking, and the total cost to fix it would be $40. The van ran great after that and I sold it shortly thereafter.
Since then we've taken cars in for brake jobs and a couple other minor repairs and they've done a great job. I highly recommend them.
