Seen this before, it's from Fifth Gear, but:
One bucket wash? Doing wheels after wash? Bit aggressive on the towel dry? Dunno, my initial thoughts on seeing the clip was that we have better detailers around these forums and Autopia.
Not discounting the guy's abilities though. Clearly he must be very good to be working on all those high end cars, and it's quite possible Fifth Gear production wanted him to simplify the process as much as possible. But I'm not blown away based on that clip alone.
