#1 is lame to me - makes this pretty girl look over-flirty.

#2 and #3 is sweet though - shows her emotion from inside #3 needs a bit more ideas on the poses though, she looks like she wants to fall asleep.

Anyway, I personally don't like the car audio show sets, the girls don't look THAT pretty compared to some models I've seen others shoot. And yes - I think the girl should compliment the car, not the car compliment the girl.
