Actually, the Toyota Prius (I think that is what is called) has good leg room for adults.
However, we know some people who have become grandparents and they sold them when they started haul the infant seats around.
Car seats and more than two adults does eliminate a lot of the PC cars.
I got to drive a Prius (some audience members at my carillon recital offered), and the only way I can describe my experience is that the car feels flimsy.
Weird thing to say about a hunk of metal, but it just didn't feel well-made.
