Mine is totally stock with 12K smiles on it. I have a 99 Ply Prowler, 04 Corvette Lemans Commemorative, 03 Chev SS pu, 00 Lightning, MB SL, 82 Vette Collector Ed., 00 Dakota R/T and they are all stock. I just prefer them that way, but to each his own. I have seen durability decreased by performance mods too often in my 52 years. Not that I am keeping any of them for "collector items" or "Barret-Jackson candidates" in 20 years, but which would you rather have.....a totally stock 67 Shelby Mustang, 435 Vette, Boss, etc. or a modified one?........I'm just sayin'.
