904 Boyz

Built in '64 and '65, it still stands as one of the better designed Porsches of all time. It had a fiberglass body, 4 cylinder engine and the 100 built in '64 cost under $8,000 each. No, originals don't pop up on eBay every couple days, nor can you find one on Craig's List, but I'm sure if you make your rounds at the auctions you could find another for just shy of $878,000.
