I was wondering which one would be better? How much in general does the Auto body shop charge to install a wing/spoiler for my 06 TL?

I did a price comparison, IF i was going to order the OEM spoiler which cost about 450 (shipping & tax including) and get it installed at a autobody shop (maybe around $100 or so?) would be cheaper, but If I get it installed from the dealership, it would be probably around 600 after tax and discount plus i get dealer warranty as well.


But i don't really know how much they charge to install it. Im from the Bay Area, so maybe that would help.

Any Help?
