I just say why advertise for free, i don't even like the fact that with my own car i can't take the nissan emblems off without having to fill in a big hole. Nissan didn't give me a discount to advertise for them, i should have the option to take it off without having to do anything else. If you want the stickers, why care want we think ? It's your car have at it, just don't get upset if most people think it looks like poo.
