Top Risk Areas
The systems that tend to fail first on the 1984 Mazda 626, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

At this mileage, the car is practically new in terms of mechanical wear, but even at 30k, age-related issues like dried rubber hoses or initial rust formation may begin to appear. Focus on fluid changes and inspection.
Maintenance Zone
This mileage typically triggers major preventative maintenance. The timing belt (if applicable) is due, and various fluids should be refreshed. Minor suspension and brake wear items may start to appear.
Elevated Risk Zone
Beyond 90k, the likelihood of age-related component failures increases significantly. The carburettor may require a rebuild, the clutch could be due, and electrical gremlins become more common. Rust progression accelerates.
High Risk Zone
At this mileage, the car is truly showing its age. Expect significant wear across all systems. Major electrical issues, transmission overhaul, and extensive rust repair become distinct possibilities. Thorough pre-purchase inspection is c…
