what's the SMARTEST way to remove a plastic dealer decal from my G without leaving a mark on the car???

bring it to the a$$hole dealer who put it on and make them remove it.

hell yeah...i HATE it when the dealers put those tacky things on cars...

I just peeled it right off, then after you wash the car it will be gone. Since the car is new, the adhesive hasn't quite settled yet.

Use a hair dryer to soften the glue and pull off. I removed one from a 9 year old Explorer last year and there is no trace of it once it was removed.
