🚨 What to check before buying
Overall risk score: 10/10
Serious risks
- Injector sealing rings: Copper injector sealing rings leak combustion gases — carbon buildup around injectors. Easy fix.
- Car is 23 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
Additional notes
- 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.
- BMW X5 diesel is the top luxury SUV in Bulgaria (1700+ listings). At 200k+ km: timing chain, DPF, turbo, swirl flaps, transfer case, and air suspension (if equipped) are all potential failure points.
- Diesel car from before 2018 with very low mileage suggests city-only use — DPF is likely clogged or has been removed (illegal). Check DPF status and EGR condition.
- BMW 730d (150+119 listings, avg 155-177k km, €35-37k) — flagship technology depreciates but repair costs don't. Air suspension (€2000+/corner), laser headlights (€3000+/unit), gesture control failures, ZF 8HP at high mileage. B57 engine is reliable but service intervals are expensive. Annual maintenance €3000-5000.
