Any RR outposts in Germany?

I'm just sorting out a trip to Wolfsburg in mid november and its occurred to me I may be able to find some bits I need for the covin peetle 911 thing (link ) I'm building on germany ebay. just wondering if there are any RR guys in western germany that I could get some small parcels delivered to, then collect on the way back from Wolfsburg?

I'll be in a estate car so could carry stuff from the UK for folks.

cheers
Matt
