Hey I'm looking to buy a Datsun 1980 B210. It runs real smooth and everything seems to be in order but I'm not really sure how many extra miles I can put on it since it already has 156K. I'm also not really sure what problems I might run into in regards to the engine. Another thing is that there is no passenger side mirror and don't know where I could purchase one. I would prefer it to be original but I'm ok with whatever seems to fit. Thank you!
