Honest, great communications, and very up front, no surprises.
I have a Ferrari, and my car was hit and a small dent was left, about a foot wide, in a bad location. Its difficult to find a good repair shop, because everything that happens to the car makes it lose its value. I dropped off the car at Executive Auto Body, and they kept me updated about the repairs and also minimized the amount of repairs as much as possible. The technician was a straight forward guy, he worked on the affected area and worked with my insurance company and did all the paperwork. I got the car back a week before it was scheduled to be finished, detailed. Knowing how to detail a Ferrari is important, and they took good care in the right way. The biggest point for me was trust. They earned my trust. Some friends of mine have been there as well, they all had good experiences.
