So, whats the coolest, oddest most expensive car etc you have sat in, driven, ridden

Oh man, do I have a LOT. As some of you know, I worked at the Chrysler Proving grounds for many years. I was part of the Performance and F/E team so I got to test a lot of way cool things. Here is one, anyone remember the ME412?

What every happened with that? only found out about it from a video game
