I had a similar experience last week- saw a new Defender enter the parking lot of a Lifetime Fitness, so I followed him and pulled up beside. Asked him how he liked it and he replied that it was pretty nice and the first one sold in St Louis. Then he said, “That’s a cool truck- what is it?” I replied that it was a 1990 D90.
“Wow- thought it was older than that. Who makes it?”
I said it was an older model of what he had, a Land Rover, and he replied, again, that he thought his was the first sold in St Louis. I decided to give up after that.
