🚨 What to check before buying
Overall risk score: 10/10
Serious risks
- Cooling system plastic parts: Expansion tank, thermostat housing, and water pump are plastic — fail with age.
- VANOS seals: VANOS solenoid seals harden with age. Causes hunt idle and loss of low-end torque.
- Car is 27 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
- Higher mileage (232,511 km) — check for timing system condition, turbo health, and suspension wear
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.
