I know someone that had a HVAC business with several trucks, and sold an old van to a handyman who had done some work for him. The business got a call a year later from someone complaining about a door or something "they'd" installed... Which of course turned out to be the handyman still having the original logo and phone number on the side. I think the deal was he was supposed to remove the logo, but of course hadn't yet. They finally got him to take it off, but the lesson definitely was don't sell a vehicle with your company logo still on it.
