I'm not a huge fan of most of the sub-compacts that are being offered. To me, they are too small and mostly too underpowered. If you live in a city and that's the only type of driving you do, they are probably fine but if you do any other type of driving, you're better off with a larger car. At any rate, I set out to seek out what I thought what the ugliest of the show.
So if I had to pick a winner of the bunch, I'd have to go with the iQ. Scion is a division of Toyota and Toyota is normally pretty good at making smaller cars. I don't understand why they would go the route of the Smart Car and make an ugly econo-box.
