yeahr, WAY pre face lift...the K10 micra was born in '82 !!
Im guessing that the original near side was probably deliberately over-magnifying to compensate for the distance it is from the drivers eyes....???...then nissan/datsun realised how much of a stupid idea that was.....
I think teh wing mirros on teh more recent K10 are still curved..(the rear viw is always perfectly flat) but may be this earler one had an exagerated neearside???
