Oh man, C5s are simply the best bang for the buck IMO. They're affordably priced, plentiful (many lower mileage garage queens) and are gorgeous, powerful beasts. The aftermarket is crazy full of performance parts for cheap and you only have to spend a weekend's beer fund to add another 100hp.

Even up against a Miata, a C5 is the best value around but it won't last forever...and I love Miatas!
