Ok, its done, THANK CUFK FOR THAT
Acoustic was from ebay, everywhere else seemed to do 1X2 meters, I got 1.4 X 3M for £25.
The glue I went for in the end was evo Stick Adhesive from Wilkinson's, this stuff is perfect, brushed it on both the headliner and carpet, left it for about 10 - 15 minutes then pushed them both together.
This carpet is wicked, It gave me no problems with creasing, so easy to lay as long as you let the glue set. This is the most important thing!
Its took a while as I did a section at a time.
Here some pics now done, just needs fitting.

Here where the visors go I had to be careful and take my time, managed to get the carpet stretched in all recesses nearly perfectly. The glue needs to be tacky here before applying carpet.



Used super glue to tidy up the rear, super glue does soak through so had to be careful.

Il get some pics up once its in the car
