My biggest fear with car troubles is that I am most likely going to deal with dishonest mechanics telling my I need to spend 500 bucks when the fix is really only 80 bucks.
I found grease monkey and found them to be honest every time I go there. When other shops tell me that it would cost 1500 bucks to fix my check engine light, grease monkey took my vehicle, ran some tests, and said it would be 80 bucks. This is because instead of telling me I needed a whole new catalytic converter, they found that my gas cap wasn't sealing right. So all they did was a simple fix and my car was just fine. My catalytic converter was just fine.
Of all the times I have had to take my car into grease monkey, they have fixed the issue, and most importantly, I have never had to go back to them for the same problem.
My old car had 285k miles on it and grease monkey helped me keep it road worthy well beyond it had any business going.
Because of their honest business I will always seek them out to help me with any issues I have with my vehicles. They're good people.
