I'm not sure how far you can move the drivers seat back, but you can fit an adaptor boss to the steering wheel to bring it away from your knees, tilt the seat squab so you are lying back further & drop the collumn down to suit. That gives a better position for us all people (I'm 6'7"). In the end though you'll end up with your knees around your ears driving like an italian.
I have no problem with the roof but my legs and arms are to long for af comfortable fit. My knees rest on the console (the place with the radio and clock).
I think that if the seat could go just a little longer to the back it would be o.k.
make sure you move the seat all the way down with the height adjuster first (lift the height adjust and push backwards), as that restricts rearward movement, then move the seat back with the forward/ rear adjuster........
I'm also just under 2 meters and have lowered the back end of the seat approx 3 cm's. This gives more support under your thigh (lår).
My seat is not pulled very far back (a kid can easyly fit in the backseat)
The steering wheel adaptor would also improve driving position but i dont know how easy it is to disassemble the steering wheel with airbag and all...
