The first-generation Vauxhall/Opel Insignia (G09) marked a radical departure from the Vectra it replaced. Voted 2009 European Car of the Year, it stands out for its stately design, excellent soundproofing, and highway-tailored road handling. However, its very high weight (often over 1.6 tons) penalizes performance, fuel consumption, and the wear of consumables (brakes, tires). The 2013 facelift (Phase 2) corrected many early flaws, notably a messy interior ergonomics (too many buttons) replaced by a touchscreen, and introduced new direct-injection gasoline engines (SIDI). A global vehicle, it was marketed under the Vauxhall (UK), Opel (Europe), Buick Regal (North America, China), and Holden Insignia/Commodore (Australia/New Zealand) badges.
The first-generation Vauxhall/Opel Insignia is an excellent deal on the used market for those looking for a comfortable large cruiser at a low price. However, its high weight and certain technical choices require rigorous selection. In gasoline, the 1.4 Turbo 140hp is the most rational choice, provided you check the condition of the M32 manual gearbox (or favor the automatic). The 1.6 SIDI 170hp (Phase 2) is the best engine in the range, offering smoothness and modern reliability. Absolutely avoid the 1.6 Turbo 180hp from Phase 1 (frequent engine failure) and be very careful with the V6 or 4x4 versions, whose maintenance can quickly exceed the vehicle's value. Favor a facelifted model (post-2013) for better ergonomics and more reliable electronics.
