I bought a Groupon for $69, which covered their "Extreme Package" - full interior and exterior cleaning + shampoo of seats and floors + exterior waxing. I booked an appointment online with no problems. This place is not about that telephone life, which is annoying when you want confirmation or have questions that you need answered immediately.
The guy took a look at my (already relatively clean) car and spoke about upgrading me to the $99 package to include stain removal treatment. There were maybe two food stains on the backseat that would easily come out with just shampoo. He said "It's up to you." I didn't say yes, but I guess my mistake was not adamantly saying no.
When I came to pick up my car 2.5 hours later, it was spotless, but I had a $50 bill (on top of the $69 Groupon)! The $50 was for taxes, an environmental fee, and a $30 UPGRADE THAT WAS NOT APPROVED BY ME. I didn't appreciate that at all. They don't print receipts with a breakdown of all the charges/taxes, so I later realized the guy also overcharged me by $5.
It definitely wasn't a deal... I ended up spending $120 total, which is a standard price for auto detailing packages. They do a good job and they're friendly... But that's the secret. They'll swindle you with a smile! Beware.
