I am pretty skinny particularly after three years of fighting cancer (successful crossed fingers), chemotherapy etc, weighing just 63kg for a height of 1. 73M. I really don't know how larger people fit in an M3W, as I find attaching the seatbelt quite difficult. I am not going as far as remaking the transmission tunnel, as I shall probably be selling my French house in the next year or so and the M3W may go as well, although I might get it trucked back to the UK (it remains UK registered). For the time being, I will just tape some pipe insulation over the tunnel stitched roll in the leather. Not pretty but practical.
Thanks for the suggestion of the slim tunnel guys.
