Yea, I think the 5 lug was an original Saleen thing. But GT-40 heads and a '93 Cobra intake on an '88 Saleen certainly isn't! Not to mention all the other mods the ad lists. A Saleen is a collector car, I'd rather just mod a GT or LX and leave the Saleen in showroom stock condition and win trophies at car shows. This car has lost some of its collector value too, because of the mods.
If Shaolin Crane wants it because it's a Saleen, though, more power to him. To each his own. Its definitely a good looking car.
