Driver Assistance Systems:

Very limited or non-existent on most models. Some later or higher-spec variants might have featured power steering.

Connectivity Features:

None (pre-digital era for car connectivity).

🔧 Maintenance

Typical Oil Change Interval:

Every 7,500 to 15,000 km (4,500 to 9,000 miles) or 6-12 months, depending on engine type and usage, as specified in the manual.

Timing Belt Interval:

Typically 60,000 to 90,000 km (37,000 to 56,000 miles) or every 4-6 years, depending on the specific engine. Critical to follow manual for preventative maintenance.

Engine Oil Recommendation:

API SG or SH, SAE 10W-40 or 15W-40 for most gasoline engines; specific viscosity and API rating will be detailed for different engine variants and operating temperatures within the manual. Diesel engines may require different specifications.

Common Reliability Concerns:

Rust and corrosion (especially in older models), carburetor issues (clogging, tuning), ignition system problems, cooling system leaks, clutch wear, exhaust system corrosion.

Engine Mount Wear:

Engine and transmission mounts can degrade over time, leading to increased vibration and noise transmitted to the cabin.

Exhaust Manifold Cracks:

Exhaust manifolds, particularly on turbocharged models, can be prone to cracking due to heat cycles.
