Took my car here yesterday and agreed to pay £60 for the top-level wash and wax package. (A discount from the normal 85!)
They did a pretty awful job. It was extremely slap dash with dirty sections, streaks, and bits where they hadn't buffed the wax out so you could still see a thick film on the car.
When mentioning this I got told it's dust... "dust because the car has been sitting here for a couple of hours". I know what dust looks like and I know what a clean car looks like.
Really disappointing. The only saving grace was that they accepted reduced payment of £30, although they still wouldn't admit any error on their part.
