The Lotus Elise I bought had it done from the dealer. They charged me $980 for it, I'm sure it cost them considerably less. It covered all the surfaces in the front as well as the mirrors, rear quarter, and the rear bumper. I can't comment on it's durability cause I sold the car, but it looked great.
I tried to take pics but couldn't get the seam to show up on the camera. If you look in my gallery you'll see pics of the car.
I thought about adding it to the Viper, but there is some pitting already there (very minor) and feel alittle uncomfortable about applying it over a surface that isn't 100% perfect.
