Re: leg room and clutch
You have to understand that the special thick & narrow seat Chysler put in the XF is designed for people who are under 5'7" and slender.
I am 5'10" with a 29" inseam and had to perform extensive surgery to the cosmetic rear bulkhead and the seat bottom & mounts to be able to drive over 50 miles. I also needed a 3" seat belt extender since I could not lower the wheel so needed to raise the seat.
Now I can sit reclined at 35 degrees and with arms and legs nearly straight out (can stretch in place). I prefer a Jim Clark position to a Barney Oldfield.
Anyone know why Chrysler chose such a different (about 2" thicker) seat than the one in an SLK ?
