The last car I purchased had the dealership plates + stickers on the trunk and window, I told the dealership that I love the car and everything about it but I'm not willing to purchase a vehicle at that price while it has advertisements on it unless the cost gets lowered by about 3 Grand. They fought it a little , but when they realized that I was firm on it they ultimately decided that they would remove the logo on it to make the sale.

That being said never let them con you into saying well you can remove the logo yourself, cuz if you end up screwing up taking those logos off(some of those stickers are REALLY on there) you're out the cost where if they screw up taking that logo off you can always walk away or they can fix their screw up

Just make sure that you are indeed willing to walk away if it's not something they budge on, cuz it is definitely possible that they will just say well then don't buy the vehicle
