My cost was a little under 1K for the front bumper, front of the hood and fenders, lights, but that was discounted. Most likely retails around $1400 I think.
Funny you mention the keying... the first clear bra I had was hacked up from a jackass keying my bumper. If you intentionally use a key like a knife it will most likely go through like it did in my case. The person did see the clearbra though and did something worse than trying to key it, he pulled up the shit and the bumper was impossible to repair. HOWEVER - last week someone backed into my car and it scuffed up and dented the fender and the clear bra completely protected the paint underneath (on the bumper). It was truely awesome and paid for itself there.
It is brutal for a nice car to be in college, so I am glad I got the stuff. I just wish I did the doors so they didn't get keyed.
Another thing is about insurance. When the car got keyed, Allstate had the bra covered, but the claim person I dealt with did not understand how much it cost. I brought them the car and she said, "how much is that wrap, um let me see, $150 should do it." I had to nudge a little while to get them to cover the full amount after a new bumper, paint, and wrap were added, when they just expected $150...
