The Ursaab in particular, and early SAABs in general, are really cool cars. A while back, I actually saw a '71 SAAB 95 (2-door wagon, in baby puke green) in person. It was a tiny car, but looked fairly roomy inside.
Jay Leno has a two-stroke SAAB 93:

The two-stroke cars are actually fairly efficient, even if they do pollute like mad. My dad knew a guy who had one-- he said it was a really great car, even if you did have to mix oil in when you filled the gas tank, and it always sounded like you were doing about 200mph, the way those little engines scream.
