Last time I was in Belgium, I was next to a car (with THREE guys in it) and it made the smart look like my X3 next to a smart. It was a new car and try as I did, I could not determine the make. It had no badge at all (and being the car freak I am, it drove me mad!!) and after almost crashing, we went our separate ways. It was tiny and slightly round and newer and the littlest thing I ever saw.
Nowhere as cute as a smart, though.
