The above sums it up... I ended up paying $2300+tax on it (part/paint/install) after the car came in - dealer did it for me. I went with them because they were actually the cheapest for me in total... another dealer wanted $3600 firm and they didn't want to discount much off MSRP on the vehicle purchase either.

You may have wiggle room if you don't get a huge discount on the vehicle... you can haggle a lot more on this part and make up the difference (which is probably why I had to pay more than avg on it).
