I do autobody and have painted my own cars in the past. Total cost for basic materials for an entire car is less than $600, depending on type of paint, color and finish.
But earlier this year my truck tapped, quite literally TAPPED the back of an SUV when it rolled three feet forward from its parked position. The SUV owner and I had to look several times, and wipe off dirt and dust to see a 2 inch crack in the paint in the hatch.
Total repair bill? $1800 for that damn 2" crack! It's robbery and there's no way it should cost that, but that was a 'discount' rate. I could've painted his entire SUV three times for that price!
The autobody industry is out of control and insurance claims are often ridiculously inflated.
