This place washes my car very well for a cheap price. It does not leave any visible scratches on my car. The basic $3 wash does a pretty decent job. I like getting the $8 wash since it also cleans my wheels. The dryer does an adequate job, but does not completely dry my car. If you're afraid of water marks, I would suggest hand drying it right after you go through the wash.
The workers are pretty friendly, and are efficient in getting you in fast. There's a frequent buyers card that will get you a free wash if you meet a certain number of washes. Free vacuums and air hoses are located on the back. I usually park my car in the designated spots to vacuum and dump trash from my car. There is usually enough parking, but it can get crowded on the weekends. They also conveniently have a vending machine with micro fiber, window/wheel cleaner, bug remover, and air fresheners that you can purchase on site.
