what id like to know Peskarik is i know you live in switzerland and your not allowed to wash your car by law, so how on earth do you keep your white car clean!?? 
you are right, it is not allowed to go out with a bucket and a cloth on the street and do some Sunday cleaning.
I go to Best Carwash in Zurich. Nice place. Was there last saturday, and saw quite a number of

-cars there, including yellow Lambo Gallardo, blacked-out and tuned Porsche Turbo, MB AMG ML63, and a coupe of Mazeratis. Quite a number of tuned cars, especially Seats.
It is a nice place, they even have a 1000-litre aquarium thru which the recirculated water for the wash runs.
And in the evening, I was strolling downtown, and my hands were getting cold, but luckily a guy pulled up in his Ferrari, so when he parked and left I was able to warm my hands over Ferrari's engine bay's ventilation holes.

Here is the address, if you ever in Zurich:

P.S. Only washed the car twice in the last 3 months, so one wash every 3500km

I had to wash it on Saturday because the back was getting really sh!tty, the sides were fine though.
