I stopped going to the dealer too. Not very reassuring when the mechanic that is working on your Z says "this is the first engine replacement that I've ever done. Should be a good car to learn on." They didn't do very good work, and they marked up their prices too high. Hell the labor alone was ridiculous, but to jack me on the part prices too? That was BS. That was back in 2002. No more. Get a trusted mechanic that knows these cars.
