Paid for the $170 package listed on their site and left my car with them for 3 hours. The car was more or less clean already -- I only wanted residual salt removed from after the winter.
There were quite a significant number of spots inside the car that were missed that I won't bother listing. Exterior-wise, they were barely more thorough than a drive-through car wash. A lot of dirt still remained inside both side mirror enclosures that could be sprayed out easily. There was also still some dirt left on the body of the car behind the side mirror.
For the price, this definitely wasn't worth it. A groupon detailing at any other place would have been about the same.
