In another documentary, one of the earlier ones, you see when she drives it in (Like how this shows her driving out.)
I couldn't get a glimpse of the emblem though, but it's -- of course -- an expensive car. lol.
EDIT: Ahh yes! My guess was right! It's a Bentley Continental GT!
I could tell from the shot when she was driving it in; that whole meshwork thingy at the front.
