I don't like manufacturers stickers on a car. I don't like bumper stickers either. I don't even put the certified 50 state legal emissions sticker that products come with on my car.
I wish that sponsors would pay regardless of whether the sticker is on the car or not because i think it makes professional race cars look like crap (except nascar because every car is the same, so it gives some character to them), but not drag race cars or road race cars.
Stickers in my opinion, as chris said, is like putting an advertisement on your car, unfortunately it can advertise to some bad people. that's just what i think, though.
