Aren't you assuming that the collision is completely inelastic?
I would think that the car would bounce, at least some.
And in that case the ratio of driver momentum to car momentum would be larger 
in the more massive car, thus the more massive car would bounce
more, thus the driver of the more massive car would leave the seat
with a higher relative velocity.

Am I confused?
