Model Evolution
Model Evolution 510:
The Datsun 510 (Bluebird) was a compact car produced from 1968 to 1973, known for its excellent handling and performance, often compared to BMWs of the era. The 1980 model mentioned here is likely part of the successor models in the Bluebird line which Datsun continued to use, although the '510' designation itself was phased out in many markets before 1980. This manual likely covers a Datsun Bluebird (e.g., 810 successor or a late model 510 variant if still designated as such in specific regions) sold as a Datsun in 1980.
