First repair was a radiator replacement. Came in as expected on price and there were no surprises.
Second repair was the test; needed brakes and I new the rotors were cooked. Pricing was as expected but they didn't do what dishonest shops do; pretend the calipers need to be rebuilt, too (note: there about a 10% chance of actually needing a caliper rebuild, but it is a red flag as dishonest shops always tell you that it is needed).
I then took my car in for an electrical problem. They called me and said they needed 1.5 hours of billable time to to diagnose as it was, as I already knew, in the huge wire harness under the dash (bump the wire harness; car can start). They then called me back and informed me that they found and corrected the issue faster than anticipated so the bill was for only one hour. Considering I had authorized 1.5 hours with the anticipation that it could cost more, I was highly impressed.
In summation, I very reluctantly trust mechanics to be fair with either electrical problems and especially brake jobs. Its just too easy to pad the bill and hard to prove your car didn't really require the additional work or time to diagnose. For me, these guys passed the honesty test with flying colors.
