Oh, come on. It doesn't even hold a candle to the Asstek.

Once upon a time, the Vega was the ugliest car on the planet. Then came the Asstek, and it took the throne of the ugliest car, pushing the Vega to second place.

I think that, in order of ugliest first, it's now:

1. That boxy Scion car (forget its model name).
2. Honda Element.
3. Asstek ("Dude, your car looks like ass").
4. Vega.
