We're all about customizing your ride. Tune the engine and suspension, swap out the roll bars, get new wheels, re-upholster the interior, get a new paint job or wrap, get a sports exhaust, install a kick-ass sound system, or whatever. All that kind of stuff is cool, and we applaud you for loving your car that much.
On the other hand, there are plenty of car upgrades lurking at your local Pep Boys that serve no function whatsoever beyond making you look like a racist, stupid, slack-jawed, thug of a douchebag. So please, if you see any of these 10 Car "Upgrades" That Make You Look Like a Douche, please set them on fire.
