I don't even know what fins are, but I have gone the classy look and decided to let my missing hubcap (hubcap, not rim) stay off the car. It looks out of place, but it give it personality. That coupled with the old man beige color that I'm rocking really helps me pick up chicks.
To be honest, my car is in the shop because of the stupid check engine light and I'm driving my sister's 97 Volkswagen Cabrio. I look so hot with the top down, like a 16-year-old girl who just got out of high school early. Sometimes I'll even blast Hanson while wearing sunglasses that are so big they cover my cheeks, even though my cheeks have no need for sunglasses. Really.
