Worst cars have to be anything that thinks it's a four wheel drive....
...but is actually an executive school bus.
porsche cayenne
VW toureg (?)
bmw x5
new volvo thing
new range rover
lets face it most are ugly, some 4 wheel drives (shogun, disco, landy, early range rover) can be forgiven ugliness - they have functionality. But there's no justifyable reason for any of the above cars (unless some one can prove me wrong)
