I got it before 2.0. I logged in on Monday, got upgraded to whatever pre 2.0 it was, got the car. Last night I logged in again and then was prompted to go 2.0. 2.0 was about a 1.1GB download. Whatever was before it was about 68MB, which was probably the car.
Another thing of note...some in-car views have a bug where the steering wheel doesn't turn. I've seen it happen more often than not. The hands move accordingly (and interestingly, are rendered as soon as they come from behind the wheel) but the wheel is static and just turned to the left (IIRC).
