installation of the 3M Scotchgard

[Blue Mountain Raider]

Hi, i found those on ebay http://cgi.ebay.ca/2007-07-BMW-X3-3-...QQcmdZViewItem

only about $210. is the installation of the film very difficult to do properly? I'm not going to do it myself. Is having the dealer (where i bought the vehicle) do it a better idea than to use a private body shop (cheaper)?

the dealer charges $1200 for the same thing!!!! I can't imagine $1000 is labor and $200 for parts.

any ideas? Thanks very much

PS: i am a little bit worried about the installation since i heard some horror story from Denalio about the installer damaged the paint and headlights of his lovely e70. Denalio if you are reading this, how did it go with your car?
