here's some photos
one seat, radian r100 in the back (we have two, both same)
my tired 6 year old in his seat
my legs in the passenger seat while my 6 year old is sitting behind me
his feet behind me
i'm 5'2'', and when i'm in the driver's seat, i'm sitting a tad bit closer to reach the pedals, so there's even more room behind my seat......enough for an adult (when i test drove the car, my husband sat behind me)
my husband is 5'7'', and he can fit into the passenger seat the way it is set up for me, but his knees will be a lot closer to the dashboard...still doable for him
i guess i wouldn't recommend the frs as an only car.....although we have taken some 2 hour trips with it.....we just like it too much
