after doing a small amount of digging I have come to the conclusion we have know idea how lucky we are with our P6's, parts for this thing are either non existent or at a huge premium, most supplier's are non English speaking and my Dutch and German is very thin on the ground, nein and ya and im out, I think I will now fit my new stainless exhaust and propshaft to the rover, easy parts to get hold of.
