I'm gonna book mine in this weekend. Just phoned him, and he estimated the price at ?600+VAT for ALL the seats to be completely re-trimmed in black leather.
All 4 door panels in black leather, ?200+VAT.
This price is for re-trimming the sportline Recaro's. I will post pictures when there done, so if you are thinking about it AdamB, you can check what they look like.
