You should really look at the
for sale Section of this site for purchasing a used Z. Most that frequent this site take VERY good care of their cars and the car might come with some decent entry level mods that you can finance into the cost. And speaking of financing, people have a misconception that you cannot finance a private party car but you can and quite easily if the car is younger than 5 years. Most times you can get pre-qualified for a purchase amount and private party shop all day.
Help a fellow 370z'er out and buy private. You'll most likely save a few thousand and stick it to the idiot sales guy that advertises a Z as front wheel drive.
just sayin...
