Hi Ian.
Your best bet is to try and find the seats in the colour of your choice,or restore your original set!! and get a carpet set made up from somewone like coverdale!
My carpets cost £211 inc vat and deliv,and fitted well,came with underlay as well!!
They will send you a sample selection to chose your colour from,the closest light tan/sand I could find to orginal for my car was a jag colour!!
Good luck,bung us up a pikkie or 2!!
BTW!!!!
