First off, I like the Audi A8 a lot, but I think it is stylistically less engaging than some of its competitors...and I mean that in a very good way. Anyone, including myself, will agree that the A8 is an technological and engineering masterpiece, probably drives spectacularly (although I haven't driven it), and has Audi's consistently beautiful interior. But overall - and some readers may disagree - its understated styling does not get my heart pumping, and I don't think it's intended to. I admire the Audi A8 for its subdued elegance and conservatism. Buying an A8 is a low risk, sure thing.
Just because I included the A8 on a list of "boring" cars doesn't mean it's bad. Obviously, when I included the A8 in the same list as a Corolla and Forte, they are not meant to be compared...they are clearly apples and oranges. The only point I was trying to make is - from someone who hasn't actually driven the cars - that of the super luxury sedans out there, the Audi A8 has the most subdued, restrained personality.
