Carbon fiber. Vented hoods. Sport Suspension. Call it what you want, but race cars look good.
The old adage goes "win on sunday sell on monday." That's not quite the case any more, but the hyper aggressive, performance oriented look of race cars have definitely filtered down into body kits and vented hoods and carbon fiber spoilers. Sure your car might not be a track killer, but that's no reason not to make it look good.
