Touchless car wash ... whats' that ?
I assume its a car wash that somehow cleans the car but doesn't touch it ?
In any case, I would never put my cars through any kind of car wash .. you never get the car cleaned as good as you would do it yourself, inside the alloys especially, you still normally have to leather it off and you have the potential for the deaded swirl marks.
Bucket of autoglym shampoo and rinse followed by leather keeps the car looking sweet
Beamers should be banned from car washes
