My check engine light came on and it was something wrong with the catalytic converter. The mechanic walked me through all the options with prices from least expensive to most expensive with worst-case scenarios. It was the first time a mechanic was upfront about possible causes, other things that could be done, and prices. This shop had it done within 2 hours and I didn't have to spend over 1k on a new catalytic converter. They didn't try to upsell me on anything. This is where I'm going from now on.
