I'm not a fan of a decent portion of the mods I see out there. Stretching is just another. I think it looks "ricey" (or whatever term you want to insert here).
Performance mods, and some of the basic stuff like M-body mods, fine. To each their own, but I think most of the other stuff just looks dumb. Just my opinion though. You're allowed to think it looks awesome, I'm allowed to think the opposite.
