We covered the Saab-source electric postal phone company van a few weeks ago and it seems a similar vehicle has come up for sale on a website in Germany.
This is the image I showed a few weeks ago:
The vehicle that's come up for sale is advertised under the title Saab Andere and as you can see, it features a somewhat different different front end, though the rest looks very similar.

If I'm reading that information sheet correctly then it looks like it was made by a company called TJ Electric in 1974, based on a Saab 95 (rather than the Saab 99 that previously figured).
Top speed is a heady and silent 70km/h.
If someone's interested in this exclusive piece of Saabology, someone's asking 10,000 Euros for it.

The description boasts it's the only one (out of total six) that's still in its original condition. Plus that the original price tag was 14 million (Swedish crowns). So 10000 Euros would be a bargain;)
It seems the car actually is here: http://sv.wikipedia.org/wiki/Dals_Ed
