You guys have been talking about some exotic cars that very fw people could ever aford to buy and only the seriously wealthy would because of the maintenance cost. Often these cars become neglegted over the years with few people who know how to work on them and the fact that people stop spending that kind of money on them. You guys are missing a great car that has some what been forgoten, the Detomaso Pantera:

The Pantera was imported by Ford from 1971 to 1974 and had the ford 351 Cleveland. What that means is you can buy a lot of the parts at Autozone! These cars are selling in the $25k + range which means comon man can buy one and work on one. This is not like the Delorian which is a sad car, this is a performance car. Customized Pantera's are the norm. Engine upgrades being one of the most popular. There are several modified 1971-74 panteras out there running on tracks blowing the doors off of the Lambroghini's and Feraries. The fact that most could buy one, most could work on one, and it is one of the neates cars around yet it has an early 1970's style to it. I have one and it is awsome!
