My wife got hit about 2 years ago and the estimate was $550. They didn't call the police at the time so any insurance claim would have been at her fault and we would pay our $500 dedcutible and rates go up. So, we paid for it ourselves. Our insurance agent recommended Key Oldsmobile in Warren. They did a great job of fixing a couple dents, painting the right side bed (pickup) & right rear door, and replaced the taillight assembly. I would recommend them. In fact, my bumper is cracked on the IS and I am taking it there for repair as well. I'm stopping by on my way home (already made insurance claim) to have them take a look at it and list the parts they need to order. anyway, I would think that they could do what you need within your check range.

I have also heard great praise for Auto Metrics in Royal Oak. Something tells me they are kind of expensive, though.
