On the Cadillac ATS: I love the idea that GM finally seems to be getting it's poop together and is beginning to build cars that people actually want to buy rather than mostly settling for. It is a good thing that Cadillac and Buick can openly say they're gunning for BMW and not get laughed out of the room.
Having said that, I absolutely loathe GM's interior design. It's a total deal breaker for me. Why does the interior of every GM product have to look like a rejected star trek prop? This isn't new, they've been doing it for more than a decade. And then they go a throw on a wood-trimed steering wheel. WTF? More is not More. When it comes to car styling more often than not less is more. BMW get's it. GM does not (yet).
