Hi Sumith, Datsun B210 will run OK at high elevations (2km height). Every 1970-era car will run a little off at high elevation, because carburetors do not self-adjust. Some newer ones do, starting with 1976 California B210, but those are special cases.

Datsun B210 does fairly well offroad, on unpaved and bumpy roads. No problems.

B210 does well on long, steep grades. Just put your foot down and hold it down. It can do that for a long time if the engine is in good tune and the radiator system is working well.
