I see that Greenland MX has a UK website now. I've dealt with one of their Spanish outlets with good results, so I wouldn't hesitate to use them again.
I know they had Polisport upgrade kits for the '01 models. I've got a '01 XC 200, but the oem plastics still look good so I'm sticking with the dated look for now.
You'll enjoy that bike once you get it sorted to suit you.
