At this mileage, a well-maintained M5 is likely to be operating near its prime. Focus on ensuring all fluids are fresh, rubber components are supple, and preventive maintenance items (belts, hoses) are addressed due to age, not mileage.
Maintenance Zone
This is where age-related wear starts to become more apparent on original components. Expect to address suspension bushings, possibly minor electrical gremlins, and ensure the cooling system is robust.
Elevated Risk Zone
Major service items become due. The engine's ancillaries, fuel system components, and significant suspension parts will likely need replacement. Electrical issues can escalate due to wiring harness degradation.
High Risk Zone
At this mileage, the M5 is truly a classic requiring significant restorative work. Engine internal wear, transmission refresh, and widespread electrical repairs are all possibilities. Comprehensive budgeting for a full overhaul is essent…
