I'd be happy if it was merely 12kms. As many others have stated, the cars do have to be driven around a bit - like off the production line, onto a truck, onto a boat, off the boat, etc. If you are getting the car tinted, expect them to drive your car to the tint shop
I'd probably complain if the car had over 50 kms on it.
ps. My brother bought a Subaru Liberty 2 years ago - we went to the dealership, and we drove the unregistered car (with a trade plate) at 8kms. When we took it back, it had 20kms or so - the first couple of kms, the car emitted all sorts of fumes (I could smell it in the rear). It cleared up after a bit more driving. Strangely, he ended up buying that particular car
