Damn, three of the four cars I absolutely hate the look of have already been mentioned (Aztek, Element and xB). So I guess I'll be the first to name
Toyota FJ Cruiser.
When I first saw it, I almost crashed because I couldn't believe that something like that could be put on four wheels. To make things worse, one of my co-workers bought it a couple of weeks ago and now I have to look at that yellow ugliness everyday as I pull up into the parking lot.
