I was worried about the quality for the price but when I showed up every other person there was a Porsche owner who had clearly been there before so I couldn't really get too protective of my little Mini. Yes they may be slow if they are backed up. It's like three guys that really care and that means it's not at speed. They take appointments for big stuff (shampoo the whole car, etc) and otherwise just do an amazing job for less than $20.
