Market Position:
The Datsun 510, particularly the 1980 model, represented a period when Datsun (later Nissan) was establishing its reputation for reliable, economical, and increasingly sophisticated compact and subcompact vehicles in North America. It competed in a segment with popular models like the Toyota Corolla, Honda Civic, and American offerings from Ford and GM.
Competitive Analysis:
The 510 was often praised for its handling characteristics, derived from its independent rear suspension (on many models) and its Japanese engineering focus on efficiency and durability. The 1980 model year saw the continuation of this philosophy, facing stiff competition from increasingly refined Japanese imports.
Key Features:
The 1980 Datsun 510 offered a balance of affordability, fuel efficiency, and a surprisingly engaging driving experience for its class. Its robust mechanicals and well-engineered chassis made it a popular choice for everyday transportation and also a viable platform for enthusiasts.

The manual would provide diagnostic steps for these common issues.
Filter Part Numbers:
This manual would contain specific part numbers from Datsun/Nissan for oil filters (e.g., 15208-H7200), air filters, and fuel filters. Cross-reference numbers from aftermarket manufacturers would also be detailed.
Brand Heritage:
Datsun, the precursor to Nissan in many international markets, built a strong reputation in the 1960s and 1970s for producing reliable, economical, and often sporty small cars. The Datsun 510, introduced in 1968, was a pivotal model that significantly boosted Datsun's presence in North America, often referred to as the 'BMW for the common man' due to its sophisticated engineering for the price.
Model Evolution:
The 510 went through several iterations and facelifts. The 1980 model year represents a later stage in its life cycle, often incorporating minor styling updates and engine refinements to meet evolving emissions and safety standards. It retained the core strengths of its predecessors, offering a range of body styles including sedan, coupe, and station wagon.
Production:
The Datsun 510 was produced from 1968 to 1973 globally. However, in certain markets like North America, the 510 nameplate was effectively replaced by models like the Datsun 200SX (S10 chassis) and later the Datsun/Nissan Stanza. The specific 'Datsun 510 1980' listing in the product information might refer to a regional continuation or a model very similar in design and engineering that carried the Datsun nameplate for a brief period before the full transition to Nissan. More commonly, a vehicle from this era with similar characteristics would be badged as a Nissan. This manual likely covers the final iteration or a specific market variant that retained the 510 designation.
