I'm 6'6" and I was standing up on the curb/sidewalk.
I actually fit really well in this car, no one can sit behind me but other than that I fit great I had to tilt the wheel up a little otherwise on long drives my knee gets really sore from being bent sideways.
and about the WRX Matts yea I got them from the subaru dealer they just say SUBARU on them and are really thick deep groved rubber mats.. I'll put a picture up sometime. They are for Impreza/WRX but fit perfect in the STi also. $50 from the dealer. And yes Carter subaru was exellent.. no hassles at all it was easy I drove up there on a sunday traded my truck in financed the little bit left over and drove home in an STi. MSRP..there was no BS at all.
