My job involves remarketing cars through auto auctions. Lots of repossessed cars there. I’ve been at the auction lots many times and have seen lots of “stuff” in those cars.
Every couple of months or so the police K-9 units come in a do a sweep of all the inventory. Quite an awesome thing to see. Those dogs and their handlers are the BEST!
My advice: If ever you buy a used car - - Be sure it was inspected (or do it yourself) for contraband.
My boss was most afraid of a dead body turning up in a car truck or under a blanket in a rental truck. That would be bad for business.
