Additional notes
- 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.
- BMW X6 diesel (199+154 listings, avg 148-176k km, €36-39k) — bought for image, expensive to maintain. Coupe-SUV body means unique (expensive) rear glass and body panels. N57/B57 3.0d is reliable but: transfer case service €1000+, adaptive dampers €2000+ per pair, 21-inch+ tires €1500+/set.
