Driver Assistance Features:
Optional Anti-lock Braking System (ABS). Primarily focused on mechanical systems rather than electronic driver aids.
Connectivity Features:
N/A (No modern connectivity features like Bluetooth, USB, etc.)
Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months (refer to manual for exact recommendations based on driving conditions)
Major Service Intervals:
Spark plug replacement, coolant flush, brake fluid flush, timing belt check/replacement (if applicable for specific engine variants, though M20/M30 are chain-driven)
Engine Oil Type 528E:
API SG/SH, SAE 15W-40 or 10W-40 (check manual for precise viscosity and BMW LL-98 specification if available for period)
Engine Oil Type 535I:
API SG/SH, SAE 20W-50 or 15W-50 (check manual for precise viscosity and BMW LL-98 specification if available for period)
Coolant Type:
Ethylene Glycol based antifreeze, BMW approved (typically blue or green)

Common E28 Issues:
Cooling system leaks (hoses, radiator), fuel injector seals, front suspension bushings, rust (especially in wheel wells, rocker panels), electrical component failures (e.g., dashboard electronics, window regulators), seized heater control valves.
E28 528E Specific Issues:
The 'eta' engine (M20B27) is known for lower revving characteristics and can be prone to head gasket issues if overheated. Early models had less robust fuel injection systems.
E28 535I Specific Issues:
The M30 engine is generally robust but can experience oil leaks from the oil pan gasket, valve cover gasket, and front crank seal. Timing chain guides can wear.
Bmw Legacy:
Known for performance, engineering, and driver-focused luxury sedans.
E28 Platform:
