BMW 520 1994

🚨 What to check before buying

Overall risk score: 10/10

Serious risks

• VANOS rattle: M50TU VANOS unit can develop rattle — seals wear out. Rebuild kits available for €50-100.
• Cooling system aging: At 25+ years old, all cooling system components (radiator, hoses, expansion tank, thermostat) should be replaced preventively.
• Oil pan gasket leak: Cork/rubber gasket between block and oil pan can seep oil. Common on older BMW inline-6 engines.
• Car is 32 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
• Very high mileage (271,483 km) — expect suspension, drivetrain, and turbo wear. Thorough pre-purchase inspection essential.

Additional notes

• Older BMW with 200k+ km will likely need suspension refresh (control arms, bushings: €600-1,200), possibly cooling system components (water pump, thermostat: €300-700), and various sensor replacements. Budget accordingly.
• Vehicle is 15+ years old. Age-related issues: rubber seals/hoses degrade, electrical connectors corrode, suspension bushings wear. Not specific to any engine, but expect €500-1,500/year in age-related maintenance beyond normal service items.
• Any car with 200k+ km requires extra scrutiny. At this mileage: suspension components are worn (bushings, ball joints, shocks), seals and gaskets are hardened, electrical connectors corrode, and major components approach end-of-life. For luxury cars (BMW, Mercedes, Audi) the cost of 200k+ km maintenance can exceed the car's value. Always get a pre-purchase inspection (PPI) and budget 15-25% of purchase price for immediate maintenance.
