I posted this link elsewhere and an American Messerschmitt owner in Germany replied with this:
For those of us who got to see the prototype when Fend was still alive can tell you that it was a project that was half finished when he died. When it was displayed at the yearly meeting that was held in Regensberg 1999 most of the instruments were either phonies or decals. Fend was taking deposits of 10,000 DM's at the time and was going to have it in production within two years. I purchased a set of his sales information packets but as I had got burned on the purchase of a BD 5 earlier in my life that I even had a production number for (ready in six months when I paid the final payment) I am hesitant to drop money for something that has not even been tooled up for. Fend was a little upset with me when I asked if he had done a marketing survey or a production cost analysis. The answer of course was no as this vehicle was truly hand made, mostly by Fend's friend and assistant (also his landlord). I cannot remember his name [added: Baptish Muehlbauer] (Fend's right hand since 1953) - I had some great discussions with him. He received the Fend 2000 after his death for settlement of monies owned to him by Fends estate.
The guy (Ludwig Staedele) who ended up with it, traded his really nice Tg 500 and trailer for it. Ludwig then finished most of the vehicle to include having to invent a wiper system gear drive and unit for the complex curved windshield (windscreen). He spent a lot of time sorting out the suspension as above 40 kmph as it was downright dangerous. After he spent a lot of money and almost five years of work he finally received a German Road Inspection for it but it is still restricted to 120 kmph (about 75 mph) but Ludwig said that above 100 kmph was putting your life at risk as it tended to wander all over the road. He has had it at several shows and displays since he received the plates for it. He was still working out the bugs but felt that it was almost 98% finished. The front suspension would have to be completely redesigned and replaced as Ludwigs had already made several changes to it that the German Safety Inspectors required him to do,
I have to say that I was quite surprised to see that he was selling it or that it already sold it to those folks as he did not say anything to me about selling it when I saw him last.
So that's relieved me of the need to rob a bank to get the F2000.....
