Tried it last night for a few, it's part of a $3.99 car package (downloadable content). I normally object to that kind of thing, but I went ahead and got this one... In spite of my natural distaste for the dlc stuff, I can actually kinda see where this one comes from. They clearly spent a great deal of time modeling this thing. The interior, dash, rear seats, etc. are all pretty darned near perfect. the sound... Well, it's accurate, just much louder than the real car is. Still, being the 'right' sound still somewhat helps to recreate the feel.
I haven't played enough to say whether it conveys the feel correctly yet.
