Yeah I'd pick the Sienna over the Odyssey too, it just looks much better.
I'm also hoping the Juke takes the Small Car over 21k category. I really appreciate it when car makers go in a completely different direction than anything else. It looks different (looks great IMO) and has a wonderful powertrain. If I wasn't married with a baby (ie. I was a single guy), the Juke would be pretty high on my list.
Mazda2, Juke, Sonata, Regal, Equus, R8, Mustang, Sienna, Sportage, Sorento, R350 BlueTec are my picks.
Car of the year has to be the Sonata in my mind. It went from middle-of-the-pack to class-leading in so many aspects. Especially when you consider the full line-up of engines... I don't remember a vehicle redesign this drastic in all aspects.
