This place is a scam. The guy refused to take my groupon (which was prepaid) because I wouldn't purchase his upgrades. He wanted an additional $120 to clean my car even though my voucher was prepaid. He condescendingly called me "Hon" throughout our exchange. He told me he would not clean my car and that I should contact Groupon for my money back. I wonder how many people schlep out to this place only to be ripped off. I left feeling frustrated, angry, and like someone tried to take advantage of me. I should also mention that the customer who was leaving as I was arriving was irate because her ipod charger was coincidentally missing. Perhaps it was for the best that they wouldn't clean my car, I still have my CD's, GPS, and designer sunglasses safe and sound. Caviat Emptor! Buyer Beware!
