It's a self-serve car wash that has enough bays that there's not usually a line. Convenient location.
Hoses that make washing most types of personal vehicles a breeze.
I would have rated it higher, but the change machine has never worked in my five times there and the length of each cycle could be about 30 seconds longer. Said another way, be sure to bring plenty of quarters with you.
I've never tried the credit-card machine.
