The Benz in your first photo is so old. At least 3 generations older than the present style. From my memory it would be in the mid-1980's era - ie 25 years old.
the streets are so clean, probably because of a shortage of resources/materials, there is not much garbages!
if NK is to change, there could be lots of business opportunities!
It looks very similar to the cities of China in early 80s. However, as in China, when economy growing, things gonna be changed rapidly (in about 10-20 years).
Many thanks for sharing the reality in North Korea.
