Question about detailer/dent removal from NAB (www.nabinternational.com), located off Rt 1 in Alexandria, south of Wagon Works and behind Jack Taylor's used cars and the Exxon.

Has anyone dealt with them? I need to clean up my bumpers before selling a 2002 530i. They are also going to repair a small dent on door. Here is what they quoted me:

Front fender (scratches) $175.00 - Wet sanding surface;
Rear fender (scratches and cuts) $295 - sanding/prime/paint;
Ding (small) $195
Vehicle cleaning $30
Shop materials $95
Waste disposal $20
Total $810.00

Might be a bit excessive but if makes me another $1000 on sale of car will be worth investment. How does this pricing look and does anyone have any experience with them?

Thanks.
