I asked for NO dealer markings on the car. Passport couldn't help themselves and they put a sticker on the back of the RV mirror but I did manage to avoid the Passport frame.
Anyway - the sticker on the back of the mirror was a cinch to remove - just peel it off. You'll have to remind them a bunch of times because that's there standard practice.
Aside from that - they are a great dealership. Well worth the slight inconvenience of peeling off a sticker.
