When you think that you've narrowed it down to a particular shop, check with the Better Business Bureau to see if any complaints have been lodged. Remember that you may find they have a few, but no business can keep everyone happy. Talk with the shop manager if you have any questions or concerns.
Take a look around the shop. Is is kept clean? It won't be sparkling clean due to the type of work, but you shouldn't see dust and filth and chemicals spilled on floors.
Ask to see their work. They should have before and after pictures of their work and will also have cars they are currently working on. Do they have letters of recommendation? A lot of business keep letters from happy customers.
Do they give any type of warranty? Some body shops offer a limited warranty.
Finally, use your gut. How are they interacting with you? Are they taking the time to answer your questions completely or do they seem put off by them? If they seem put off, it's time to look elsewhere.
