And thats why you never buy demos. They treat them worse than used cars.
Well, I would NEVER buy a USED car! Only certified "Pre-Owned!" LOL! "Pre-owned," indeed.

Either way, they should have at least cleaned that demo. I agree with bombing them in the survey and spreading the word. In the comments section of the survey, tell them to pay their technicians more than minimum wage so they can afford to clean vehicles properly.
