We have never been fans of a lot of signage on our vehicles. We always debadge the rears. We left the "Land Rover" on the front of our LR3 and RR, but the rear is blank on both, other than the green LR emblem itself.
When I had an FJ Cruiser Trail Team I had people asking me to buy the "special edition" badge - I though that was hilarious!
I see people all the time keep that little advertising sticker from the place they bought their vehicle (which is really funny when the place is called Cheap Heaps! No joke, we have one!).
Some people even leave on a front license plate advertising their dealer (we do not even use front license plates here in PA).
I guess everyone is different. This guy really cracked me up, he took his Toyota Yaris and made it into a "Cadillac"! He even had emblems on the sides of his car too.
