A car that I've never heard of, had literally no idea of its existence whatsoever. Which made opening the page very fun indeed. It's not often that I get to base my Cool Wall vote completely on an untainted, first-time-ever-seeing-this-car reaction.
When that first image loaded, I said "wow," and then realized I had a large smile on my face.
Coolness is about initial, visceral reactions, about the way a car makes you feel without even thinking about it. Who cares that it's slow? That it's FF? That it's not a muscle car? Most people, that's who. Most people will see this car and just smile. They'll have whimsical thoughts about a lazy weekend drive at the wheel and a pretty girl in the passenger seat. That's cool. No, wait, that's sub-zero.
