Dealer asking €18,331 — 59% above dealer benchmark (€11,500). Severe overpricing; walk away unless warranty covers DPF/EGR failures in writing.
100k km is within range but low for 8 years; verify full service history now — DPF regeneration issues kill these cars on short urban runs.

Pricing is tight, the middle 50% of Opel Insignia diesel examples sit within a narrow €1,525 window. Condition and history matter more than negotiation here.
2
Normal market turnover at 27 days average. You have time to be selective, but don't sit on a great deal.
3
Demand score of 94/100 is high. Fairly priced examples sell quickly, set up alerts and be ready to move fast.
