Boeing does this with their seats in the factory too, they put a picture of a Lamborghini on the seats since they cost the same.
EDIT: Yes, it's hard to believe a seat costs the same as a Lamborghini, that's exactly why they put the picture on it. This is mainly for the first class seats, though rows apparently cost about the same too.
