I sit such that my hands dangle over the top of the steering wheel with my arms out stretched, so there is a bend when holding the wheel at 9&3. wheel is all the way out and all the way up.
Belly and chest are 18" from the airbag, seat is almost all the way back 3 notches from the furthest back position, feet are on the petals and all the way down with my legs ~80% extended.
Typically when driving my arms are on the armrest and the drivers door. when really driving they are at my sides.
seat is up almost straight, my head is comfortably near the head rest, but not touching all the time, most cars I want 3-5" between my head and the head rest, but in my golf it is about an inch.
