It's $5 for the basic wash, then it's $8 if you include wheels, and so on the price goes up.
For five bucks, it's not a bad deal at all (plus, you get a free car wash after purchasing five). There's a very similar car wash place called Wash Wizard down the road, and they charge $8 for the basic wash (plus, at wash wizard you have to purchase 8 car washes before you get one free).
Free vacuums after your car wash. and a dust pump. I witnessed some customers waxing their cars. So, I guess you can do that as well.
