just a word of caution.. a PT build takes a fair amount of cash before you have somthing that will accelerate, corner, stop and look good.... so dont start out with a car that has little or no resale value.. i have done stuff to my BU that would put a 1.gen in the 50K resale value bracket, give or take alittle... and now im stuck with a malibu, thar cost almost the same to build but is impossible to sell at 1/4 of the cost compared to a 1.gen....
i think an early 2.gen will be less of a bad investment than an MCSS... or atleast do an aerocoupe, BRP (sponsor here) has one for sale that looks decent.. perhape you can get him to throw some of his parts in when you bargain over the price...
