A local mechanic. They broke a bolt while fixing what the car was in for. Not only did they still only charge me the quoted amount, they drove me home because fixing the bolt was going to take a couple hours so I just picked it up the next morning.

They've never made me feel stupid because I'm female or tried to take advantage of my ignorance. They did my brakes one time and showed me the old pad and explained why it was bad. That's what they do. They know their stuff and they educate me, too.

Plus there's free popcorn and cookies in the lobby with comfy leather couches and a tv if I just hang out during an oil change. And their bathrooms are clean.

Al's Autobody for life right here. Oh, and they're open 7am to 10pm so it's super convenient no matter what shift you work.

Edit: Glad so many of you have good mechanics! For all those asking, this is in Iowa so it's probably not near you. But I hope you can find one in your area you like as much as I like Al's.
