Everything went great, just would have liked to get a little feedback on an ETA when they started on job. But I don’t really have anything bad at all to say.

Jim contacted me right after the claim was sent out, and was very professional. Within a few days, they had me drop off my car and had it finished a few days later. I would highly recommend them to anyone needing their car repaired!
