Sorry, but if you were expecting Robert Downey Jr. to be driving a crazy futuristic Acura concept car off the movie set, we have to let you down. He's kind of got this important thing called a family that he's got to drive around. Baby seats don't exactly fit too well in $9,000,000 two-door coupes. The Audi A8 he's got is still extremely nice, though. If it's a 2011-2012, like we believe, it started at $78,000 and delivers 372 horsepower to its quattro all-wheel-drive from a 4.2-liter V8. An eight-speed sedan as a family car sounds like a great compromise to us.
