My personal ``favorite'' is the Lincoln Navigator. It might be smaller volume-wise than some others, but its massive flat rear-end is bound to take the cake in pure vision-blocking surface area.

And you haven't been horrified by the abomination that is the Pontiac Aztec? There is no car on earth that has more back end than that thing. It truly is one of the ugliest cars EVER BUILT. Yet somehow it passes testing phases and people are driving them. Then again, it seems that more people have won them on game shows than any other car. Is that saying something??
