Dnepr stopped building in the nineties. I got mine by buying a bunch of parts in Canada and building it myself. The frame welding is crude but resonably strong. The nuts and bolts were soaked in salt water before assembly. ( Russian form of lock tite ) the nuts and bolts are of inferior metalurgy and break or strip easily.
I put mine together with American metric stuff. The lectrics are undependable and the wires brittle and subject to breakage. The older engines are better that the same age Urals, but in the last few years Dnepr
did not always pay workers on time and a lot of units suffered from various sabotages. Broken drill bits left in holes before assembly and such.
If you take it apart and put it back together using American hardwre and Bosch electrics and american wiring, you might be able to get a sort of decent rig.
If you can buy it for a completely dirt cheap price, you can use the sidecar on a real motorcycle and sll the bike for parts or hang a mailbox on it or something.
