AI Market Summary

Diesel engines deliver solid fuel economy and torque for motorway cruising; Insignia chassis is well-balanced and spacious for long-distance comfort.
Priced fairly for current market—strong 35% year-on-year rise reflects general diesel demand, but watch for overpriced outliers above €10,500 given mileage clustering near 168k km.
DPF clogging is the critical weakness: short-journey driving (school runs, city) causes regeneration failures costing €800–€1,500 to fix; EGR carbon buildup triggers rough idle and limp mode. Check service history for regular motorway runs and DPF cleaning records.
Before buying, request full service history and have a pre-purchase diagnostic scan performed—limp-mode faults hide expensive repairs. Inspect window regulators and test all dashboard switches for electrical gremlins.
