I hated it on my black Camaro, it eventually will shrink a bit, turn slightly yellow, turn a little dull, and everytime you wax your car you'll spend another 10 minutes with a soft tooth brush getting the wax off around all of the different pieces. Another problem was that it did not cover everything on the front end so the car did end up looking like it had 40,000 miles on it anyway. The signal lights, fog lights, and portions of the facia itself still were sand blasted driving on the freeway. I even had rock chips go through it and still chip the paint.
FYI, 3M does sell an adhesive remover that will work great to get rid of it.
I say get it if you plan on driving less then 5,000 miles a year and if you have covered parking at work. Here in Utah driving every day and parking the car outside during work it only lasted two years. I removed it after people started asking me what was wrong with my paint.
With that said,
I will probably just buy a roll and do it myself and cover the insides of the fenders and lower rocker panels when I get my Sky. Last time I checked a 12"x6' roll was about $40?
Remember it's only going to cost you $500 to get your front facia/hood repainted down the road anyway.
