So I called the dealer this morning and told him I want to wait 30 days before they apply the film. Told him I don't care if the body shop says we don't need to wait that long. He called the body shop: they agreed there's a very small chance of bubbles if we don't wait, so for my peace of mind it's best to wait. Dealer is gonna keep my X5 until the end of April, and apply the film at that time.

They said they'll need to pick up the X5 35d loaner that I'm currently driving, but will give me a previously owned car from their certified inventory. They are going to drive the two hours to me to swap vehicles. I told them my wife and I can make do with her vehicle for the next 30 days, but they said they want to make things right so will give me a car.

So it's still a headache, but I'm feeling better.

Note: They also told me they will now be applying the film to ALL X5 M Sports before they put them on the lot.
