I was 19 back in 77 and drove by a local Nissan dealer, they had a powder blue Lincoln Town Car 2 door on a stand out by the highway. I stopped and was looking at it. I had a 72 Pontiac Lemans. I asked the dealer to get the keys so I could look inside, he looked at me and said, "You'll be wasting my time".
I went inside, found the sales manager and asked him if they wanted to sell cars, he said of course we do. I told him what the salesman told me, he grabbed another one and told him to get the keys, and take it off the rack if I wanted to drive it. (One of those metal ramp style) I had the car at home three days later.... and never saw that salesman in there again.
