My 84 y/o father, who can't stand up straight and walks in a shuffle, went alone to a dealer and was sold a used car for $20,000. (nothing wrong with the 10 y/o 40,000 mile car he had - traded it in) I find out the next day when he calls and tells me that his cars been stolen. He didn't remember buying the new car, which was there in his apartment's lot! What a hassle cancelling the sale - paperwork's already changed at the RMV. Dealer won't return the $20K until the titles delivered in about a month! Why don't dealers have a policy to prevent this?
