I paid $200 for mine but it was worth every penny. A company called LA Tint did mine (not sure if they're a national chain or not) but used them for two main reasons. Number one, they're computerized. They bring your cars make and model up on their computer and the film gets cut electronically to perfection. Second their film is UV rated, which if you have a nice interior like mine is important. I didn't want my nice red leather turning pink on me. Plus LA Tint gives their film a lifetime guarantee. Also, I made an appointment and waited about an hour or so while they did it.
Basically, call around to see which tint companies offer these. It might cost you a few extra bucks but you'll be real happy in the long run.
