Cheers guys, its not a new carpet its second hand, guy whose selling it (on eBay) has had a look at folding it in half and said it doesn't really want to go in half so is reluctant to make the bend. Might just buy it and ask him to do it. Its not actually for a car, its going to be the base of a computer gaming setup where i re-create an M5 in my study for my racing sims. Sad i know, but guessing it doesnt have to be perfect then.
