I had to turn in a leased Mazda, and the guy Mazda sent to inspect the damages just reamed me for the costs; they were blatantly over-inflated.
I took my car to Dent Busters -- damage that was estimated to be 1200 dollars they did for 500. They were really friendly, honest, and timely.
Great guys, and a great place. I will definitely, without a doubt, go back to them for any repairs.
