SEVENTY TWO DOLLARS AN HOUR!!! Holy CARP!! Is that what insurance pays or is that what the place that you got the estimate is charging? There is a set $ per hour that insurance sets. It's been a while since we have been out of the autobody biz, and we were never in it in CA, but that is about triple what it was when we were in it about 8 years ago in FL.
And hey, you could have at least slapped 'em silly with a flip flop! LOL!
I don't know where you brought it but getting a second estimate couldn't hurt. But like MrDubya said, don't let them talk you into aftermarket parts.
What year is the car?
