Starting using them when I ran into a misdiagnosis with a previous mechanic- they found the root of the not so straightforward problem in no time! Very through and knowledgeable. Always give me an estimate and are right on the exact amount of the estimate. Willing to tell me which repairs are option, which can wait, and which need done soon, and don't suggest unnecessary "fluid flushes" or other services. Prices are lower than or within $20 of anyone else i've ever called or estimates.
