1. Wing - way too tall, it may be functional, but it looks like crap
2. Roof Scoop - cheapest way to rice your car
3. Stickers - Intrax, Pirelli, Snap-On, Sparco. Who puts a sticker for their tools on the car?
4. Flames - tacky
5. Viper Sticker/Windshield Banner - justfiable, when you do something like this to your car, you need to let other people know that they are seeing a Viper, and not another Honda Civic.
