I was on very good terms with the saleswoman from whom I bought my last 3 cars. When I stopped into the dealership a few weeks after trading-in my old Outback for a new one, she called me over to her desk in order to tell me the tale of the weirdo customer to whom she almost sold my 10 year-old Outback.
First, the customer stated that she needed to take it on a long test drive, in order to be sure that it could climb "the Kingston Hill". Bear in mind that this hill is...just a hill...and is not at all steep. The saleswoman assured the customer that the 3 liter six cylinder engine in that Outback would be far more capable of climbing that hill than the customer's ancient Corolla, but she gave the woman the keys and sent her on her test drive.
About an hour later, the woman returned and admitted that the car did indeed have very good power, but...there was just one more problem. She pointed to a used Volvo that was also sitting on the used car lot and stated that she would buy my old Outback if the dealership would swap the Volvo's seats into the Outback. With that request, the saleswoman pointed down the highway and told the customer, "Do you see that Volvo dealership? That's where you should be doing your car shopping".
As the saleswoman said, "I don't need to make sales so badly that I need to deal with nut-cases like that".
And, she was glad to report that this particular customer had never returned.
