Some people are just challenged when it comes to visual recognition.
When I had a modified 98 VW GTI a couple fought over it the same way. The woman insisted that it was a Volvo. Know of any 2 door hatchback Volvos in bright yellow paint? With the exception of the P1800 sportwagon, I don't think Volvo has made a production two door hatchback in its entire history.
On a positive note... when I went to America's Tire Co. a couple weeks ago the VX created quite a stir. There was a guy with is kid there and the guy was acting more like a kid than the kid was. He walked around the VX several times checking it out. The first thing the salesman said, without asking what it is, was "it looks like it can go anywhere." That being the long time Jeep slogan... I think it's quite a compliment.
