Much agreement.
Lexus cars look horrible to my eyes, unless they're knockoffs of a big Mercedes barge (like the previous LS, and even that looks bloated). The latest "Look Ma, my car can park itself!" LS is just weird - it looks wayyyy too long from the side.
I think Acura has the most consistently good-looking cars these days. The RSX was a sweet design, and the TL is very well done. You have to look pretty closely to realize that it's based on an Accord (a give-away is the front and rear glass). The Honda brand, on the other hand, usually disappoints because it's become so bland (see the Accord).
BMW can make very nice handling cars, but I more-often like the styling of M-B cars. Both are expensive to maintain, as you note.
I think the Germans' profits over the years have suffered due to competition with Lexus, Acura, and Infiniti. But the competition is good for all of us, and they're branching out into new brands (like the Mini).
I think the French would have a tough time re-entering the US car market. They are known (if they're known at all) for making quirky cars and consumers here have become accustomed to the importance of reliability. Building a service network will also be a challenge.
Initially, the Chinese will have to compete on price. They're used to fighting battles for decades, but one has to wonder how long they can tolerate huge losses these days. I don't expect the Chinese market to continue its 10% per year growth rate indefinitely (AFAIK, it's never happened before). When the Chinese recession comes, I would expect it to be a duesey. I wouldn't bet against it being 15 years or more before China sells more than 50k cars a year in the US. The existing big players aren't stupid either, though they act that way sometimes. If very low cost cars become important in the US, they'll ship cars from places like Brazil, Thailand, etc., to the US to compete and not simply hand the market to the Chinese manufacturers.
The 240SX was a nice looking car, too. I think Nissan would do better if they'd bring over more light-weight, small cars like that again. They should have had things like the Versa here long ago, IMO. It apparently competes very well against the Honda Fit (which admittedly is an older design).
Cheers,
Scott.
