I've been here a handful of times and have had sub-par experience.
I believe the wash itself is overpriced - most of the times I took my car (a Toyota Corolla) through there was a significant amount of missed area on my car after the wash, even the mid-high end washes. I always bring a towel to do a final dry off (mostly because the air dryer does a terrible job) and there is usually some soap left on the car, along with areas around the bottom sides and back of the car that we're not cleaned.
The employees are friendly for the most part, but one of them did sucker me in to signing up for a "subscription" 6 days before the end of the month by saying I would get free washes through the end of the month and could cancel the subscription at any time if I didn't want to keep it. Turns out the cancellation policy requires you to cancel 6 days prior to the end of the month...kinda sketchy.
Overall I'm not a fan of the value here and I'll probably go somewhere else that has free vacuums and a cheap wash.
