I have the full StoneGuard kit on my car. I've had it for about 2 months now, and I'm quite happy with the results. Unless you get pretty close to the car and look carefully, you don't notice it at all. I also have the StoneGuard Light, which is a thicker foil that covers the lights. I think this extra protection will go a long way to keep the car looking good for a long time.
I don't remember the exact price, but I paid around $900 for the full kit and the light covers including installation. My advise is not to try installing it yourself, unless you really know what you're doing, since it seems pretty hard to get it right. And it looks ugly, if it isn't done right. Be careful in chosing the place that installs it. The experience with my installer was mixed. He didn't do a very good job initially, but went out of his way to fix it up. After I complained, he re-did the doors, and did some extra trimming in some areas.
We got the X-pel kit installed on our M5. They throw in free headlight and foglight covers as well, and the whole process covers the headlights, foglights, side mirrors, front bumper, hood (to just north of the BMW roundel) and front 3/4 panels (to same level of hood) including installation came to $450. X-pel will recommend installers in your local area. I would highly recommend these kits (X-pel or Stongard) to protect the paint job.
Stoneguard recommended Rik Walters @ Detailwerks 408-378-6600. I spoke with him yesterday and seemed to be pretty competent. He wants the car overnight to insure that there aren't any water bubbles left under the film. He told he has done a bunch of M5's already.
I haven't decided what I'm goin got do just yet. My M5 is sitting in Ohio until my leasing company can get it transported......

Since you are both in the bay area, could you give some references to us where we could get stoneguard installed on our M5's?
TIA! I heard the foglight on E36 M3 break easily, so stoneguard light makes a lot of sense.[/QUOTE]
