We did the drive-through exterior only. It only took 3 minutes and was pretty thorough. There's a guy at the beginning that sprays and scrubs the bugs off your front end and side mirrors. Then you go through the machine and when you come out there are people that "dry" your car. They wipe down the windows and whatever visible water is still left after your blow dry. It was more than I expected for $8 (mid level wash). There's an attendant/cashier in the front that asks if you want "$4.99/$7.99/$10.99?" but does not explain the difference and there isn't a sign that tells you. I know we could have asked but they were getting ready to close and we only had $8. I was pretty satisfied though. However, I live in Hawaii and this kind of car wash is hard to come by there. I will recommend my in laws return with their cars.
