ZF, we have a wrx and have a turn a tot for DD and DS is in the AHR maxirider behind the drivers seat. When DH drives, DS can't quite touch the back of the seat with his toes when he stretches his legs out. I'm shorter so have my seat forward and DS can't reach when I'm driving. DS is about 86cm so bit on the short side but even when he gets bigger I imagine there would still be plenty of leg room for him, he'll just be able to kick the seat lol

So yes there will be more leg room than the turn a tot and by far more room to actually get into the car seat.
