$3 car wash signs are misleading. That $3 gets you a rinse, no soap, and no air dry. What's the point?
To get a decent wash expect to pay at least $5-6. Don't worry about all of the extra stuff (you'd be dumb to pay $10 for a wash here). It doesn't do much good.
The vacuums sucked. Which is good. But alas, only 2 stars for misleading advertising.
