East German Trabant car in Longmont

I spotted this Trabant car on Hover street in Longmont today.
If you aren’t familiar with the Trabant, it is a masterpiece of East German engeneering, still common on the roads of Eastern Europe. The Trabant was the true “people’s car” for those in the eastern block.
This is only the second time I’ve seen one in the US, and the first one I saw didn’t run – this one seemed to run well and had Colorado plates – and a DDR sticker on it. I’d be curious to know the story behind how this guy got it over here.
