Found a seller on ebay.com (US based) who sells various parts:
deutschepartsusa | eBay
I was looking at the drag link assembly as I might change it in the future and the cheapest new set in the uk I can find is around £220...whereas he is selling one at $207.99 shipped which equates to around £130....bargain I thought.
Just thought it might come in useful, how much does his other parts come in price wise after currency conversion?...maybe you more informed bunch could have a perusal and tell us what parts will come in cheaper.
Hope I've helped somehow
cheers
rob.
