How much is the cheapest sports car?

It depends on how you define sports car. Some consider it to mean only high end exotics or big V8 muscle cars. Others think anything with a peppy engine and tight suspension counts. You can get a base Ford Mustang, Chevy Camaro, Dodge Challenger, or Scion FR-S for between $24,000-26,000. You can get a base Ford Focus for around $16,000 though, and that's a pretty good handling car (the sport package with turbo gets back into the low 20,'s though). A Volkswagen GTI and Mistubishi's base model Eclipse are also in there (the base Eclipse has little power though). You can buy a Hyundai Genesis base with a turbo 4 cylinder with a lot of power for around $23-24,000, for a legit new sports car if price is the main consideration and you want legit speed that should be high on the list.
