What every 16-20 year old who's seen "The Fast and the Furious", or "2 Fast 2 Furious" is likely to drive. Usually running a ridiculous amount of negative wheel camber due to the car being lowered without getting an alignment done, wheels larger than can reasonably fit in the wheelwells (giving lots of tire rub), a 3 foot tall aluminum wing, under car neon tubing, "Type R" decals, a boost gauge (esp in a normally aspirated car), and has the overall appearance of an automobile onto which every advertiser in Super Street has barfed a part.
Required equipment includes a 5 inch exhaust tip on an otherwise stock exhaust system, a 4 million watt stereo system that, from outside the car, seems to do mothing other than vibrate the rear hatch glass, and every aftermarket gauge that the local Pep Boys carries (not necessarily connected to anything).
Not to be confused with a "tuner car", which may be quite a bit faster than anything you've seen away from a racetrack.
My friend's sixteen year old brother had a really fast Chevelle, but fter seeing the Fast and the Furious, he traded it for a 17 second rice burner.
