i dont want my car to look all cheap and shit, so should i just spend the big bucks for a leather job, or do seat covers do the trick?

seat covers do the trick until people get in your car and notice that you have seat covers. I like seat covers though. My friend has a really nice pair in his teg, and I love them. :)

my friend has the pleather sisqo dragon ones and they are so uncomfortable and ugly, he needs to be hit with a baseball bat he has everything ugly that you can put on a car on his car
