The new one (first generation)is essentially a Golf IV, so it's at least a functional vehicle. Those are almost old enough to have a historic license plate in Germany.
Maybe it was the one I drove - I found myself pushing the steering wheel in a bid to get up a relatively modest incline. I was also quite alarmed by how quickly things were passing me.
They're impressive for what they are: a vehicle engineered at a time of minimum resources and manufacturing/maintenance ability, for a specific goal.
I respect them for that. Otherwise don't care for them at all. Awful to drive (they have the same suspension as a Corvair that dumbass Nader called Dangerous at Any Speed), only with that god-awful front suspension design that has major bump-steer issues. Gutless air-cooled engine, no AC and practically no heat.
But I'm comparing it to anything built after it that didn't have the serious constraints it's designers had to contend with. I would've loved it in 1940 Europe.
