I had a stick-on type on my 4Runner a few years ago. I was totally pissed. I thought I was paying for an upgrade (at the dealer, at time of purchase) with actual pieces, but they were just stickers. If I had seen it before they installed it, I would have told them to forget it. It's totally lame in my opinion. If it's not an actual piece, I wouldn't do it.
