According to who? A quick google search brings up GT-R, Hyundai Genesis, TDi Jetta...
The world car of the year is a VW golf, which is a slightly less nice and smaller A4, both are leaps and bounds above a Camry.
There are too many factors that go into choosing car of the year, like cost vs what you get, gas mileage...whatever. Luckily German car resale value falls flat after a few years, so you get a hell of a better car than say a Camry that holds it resale value in the US a lot longer because most people have 0 taste in cars, and believe that Toyota's will last forever and get incredible gas mileage.
Now I will admit that I've only seen the new camry's, and have never been inside one. But I will tell you that its an ugly car on the outside, and looking at pictures of the interior it looks just like any other Nissan or Toyota interior...crap.
But that's my opinion. Another car I would suggest is an Acura TL (not the brand new ones), but never over a European car, plus its also FWD, just like a Camry, and that's just yucky. But the TL has an interior just as good as any new BMW.
EDIT, oh, car of the year 2007.
