Mitsubishi Pajero Sport
You might not like the styling, but it doesn't have that "bits of several cars, randomly stuck together" quality of the truly awful.
You are quite right. It's just every time I see one, it makes me cringe. I don't know how anyone can look at one and think "oh gee, that looks great". Subaru's make me cringe too but I think it's more to do with the people that tend to be behind the wheel than anything else.
As for the "randomly stuck together", there are large amounts of those cheap, Chinese brands popping up here now. Great Wall, Chery, SAIC and Foton are probably among the more common ones. They aren't necessarily ugly, just generally very plain and generic looking. You can really tell the manufacturers have just rummaged through any old parts bin and slapped it together. I drove a Chery once, never again. It takes tinny, rattly and unsafe to a whole new level.
Apart from the Pajero sport, the next ugliest car on Australian roads at the moment would probably have to be the Nissan Juke. It's just so "bulbous" in all the wrong ways.
