Active Features Active Safety: Advanced suspension for its time, responsive braking system, ABS (Anti-lock Braking System) often optional or standard on higher trims. Passive Features Passive Safety: Reinforced passenger cell, crumple zones, padded interior surfaces, seatbelts. 💡 Technology Features Infotainment Audio System: Factory AM/FM stereo cassette player with analog tuning and optional amplifier. Climate Control: Manual or optional automatic climate control system with A/C. Driver Assistance ABS: Anti-lock Braking System (ABS) was often an optional feature or standard on later E23 models, providing enhanced braking control. Connectivity Connectivity Features: Limited by modern standards. Primarily focused on internal vehicle systems, not external communication. 🔧 Maintenance Service Intervals Oil Change: Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil type. Consult manual for specific advice. Tune Up: Spark plugs, air filter, fuel filter replacements at intervals of 15,000-30,000 miles. Fluid Specifications Engine Oil: API SG or SH, SAE 10W-40 or 15W-50 recommended (refer to manual for precise viscosity based on climate). Coolant: Ethylene Glycol based coolant, typically a 50/50 mix with distilled water. BMW recommends their specific coolant.
