Now that sound's cool. I haven't seen anything like that here.
In the UK there are loads of hand car washes where a team of people, armed with jetwashes, sponges, chamois etc get to work on your car. They do a very good job for a good price, I pay £10 a go for an inside and outside clean.
I haven't gone there with my Cooper yet. I'm in that proud owner cleaing his car on a Sunday mode still!
Better still if you take you mini in for any problems to your dealer, they do a great cleaning job too.
