what kinda work do you need done? Sounds like you dont konw much about cars. If thats the case, shady shops can smell you a mile away.
The best mechanic is yourself. Grab yourself some tools and let other people be your guide. This place is a good start, like many other sites that have plenty of knowledgeable members who would gladly help, if asked.
As far as shops, I stopped taking my cars to repair shops 10 years ago.
