Having a problem with mine at the moment with glue marks left by the wrapping that would have been on the car when it was delivered.
Soap and water doesn’t remove them and other cleaners only have limited effect. I contacted the dealer (not local and a 200 mile round trip) and they suggested T-Cut. While I am sure this will work I am not about to start T-cutting a two week old car. They also left residue on the seats, stickers on the wheels and plastic covers on the interior door handles.
Just waiting to hear from them what they are going to do to resolve this. Really annoying though.
