Bought a 1970 Datsun (remember those before the name change to Nissan) 1200 from the got a whopping 50mpg and would run at 8O mph all day long with out a hitch of course it took all day to get up to 80 mph, gas was under 50 cents a gallon back then, so most people were not worried about economy ...until the gas crunch on the east coast in 1973...I was glad I had my little green Datusn. Later I bought another Datsun 1200 used and ran that one til it fell apart too. seems the bodys were prone to rust
