Well without getting into an argument I have had many NSU cars. Maybe that was part of the problem as the normal club official line was there were only x number of these cars and y of those. In that case I had a third of the Sport Prinz, a quarter of the Spyders etc over the years. Basically the figures were not correct but also the support for the certain types was not great. Thus I bought up several dealer loads of spares including 4 industrial cages of new bagged smalls from one place. VW were very hostile to NSU as a brand - they knew it was the better product I expect. There Audi was a RO 80 with a German three box body on it, the front wheel drive stuff was Prinz really. So the garages wanted rid. When I sold up the first time I offered the club the spares by dint of sending a list of parts I made up for retail sales suggesting they could make me an offer for the lot. Instead they chose to be silly and effectively 'marked' my list with price changes, availability and rude notes. They claimed to have new Sport Prinz bumpers so I called all the SP and Spyder owners and told them. Besieged with calls for stock that did not exist they then got funny about it. I therefore did two Mannhiems, took a huge amount of cash and sold the residual stuff to Mellmann who visited the club stash on his way home a did some trading with them for stock he wanted (seems a bit odd for a club to sell club stock to a trader to gain a few specific items. I leave you to work out what I think was going on). They then asked where the van full of stuff came from and apparently were really rather put out to find it was me.
I built up collections of NSU twice after this with spares to back it up and did the same thing. So the club lost the chance of obtaining a very large quantity of good spares because they preferred to play games with me. Wrong choice! Thus running an NSU now is not as easy as it could be and the prices are depressed here. Best light car I think to own and use is the Sport Prinz. Pretty, efficient, cheap to run and very under priced. A hard act to compete with. Trouble is finding one that has not been noshed is very difficult as the poor support has done for most of them. It is like looking for a perfect Goggo, there are about 3 left! The rest feature mostly ill restored cars as the prices do not reward effort. I have given up looking really, it is to depressing.
