If there is a dealership…
If there is a dealership emblem on a car I intend to purchase I always ask how much the dealer is going to pay me to advertise for them (even for license plate frames). I have gone as far to tell them if they can't remove the emblem without damaging the paint then just order a new car and don't put an emblem on it. They'll remove it. The sale is more important to them than anything else and you are the customer -- make them deliver what you want!
