Factory AM/FM radio with cassette player. Options for upgraded speaker systems.
None:
No electronic driver assistance features typical of modern vehicles (e.g., ABS, traction control, stability control were not standard or widely available).
None:
No factory connectivity features. Communication systems were limited to basic audio and instrumentation.
Oil Change Interval:
Typically every 3,000-5,000 miles (4,800-8,000 km) or 3-6 months, whichever comes first. Consult manual for specific recommendations based on driving conditions.
Spark Plug Replacement:
Intervals vary, but generally around 15,000-30,000 miles (24,000-48,000 km) for platinum-tipped plugs, or sooner for standard plugs. Rotary engines often use two spark plugs per rotor housing for optimal combustion.
Timing Belt Replacement:
N/A - Rotary engines do not have timing belts or chains in the conventional sense. The engine's timing is controlled by the eccentric shaft and rotor positioning.

Carburetor Issues:
Carburetor maladjustment, fuel delivery problems, vacuum leaks, especially with aging seals and gaskets.
Cooling System Maintenance:
Importance of keeping the cooling system in optimal condition to prevent engine overheating, which is critical for rotary engine longevity.
