The second-generation Vauxhall/Opel Insignia (Type Z18), marketed under the Grand Sport (sedan) and Sports Tourer (estate) names, is based on General Motors' E2XX platform. Unlike other models of the brand that passed under the PSA/Stellantis umbrella, the Insignia B remained a pure GM product until the end of its career. It was also sold under the Holden Commodore (Australia) and Buick Regal (North America/China) badges. Lightened by nearly 175 kg compared to the previous generation, it offers transformed road handling, generous onboard space, and an excellent price/quality ratio. The 2020 facelift brought new engines (notably a 1.5 diesel 3-cylinder) and a technological update. It is an excellent cruiser, particularly relevant on the used market for high-mileage drivers.
The Vauxhall/Opel Insignia II is an underrated cruiser that represents an excellent deal on the used market, provided you choose the right engine. For diesel use, the 2.0 Turbo D (170/174 hp) is the preferred choice: robust, torquey, and built for the highway, it avoids the serious pitfalls of the 1.6 Turbo D. The latter (1.6 CDTi) is to be avoided due to its fragile timing chain that is exorbitantly expensive to replace. The petrol versions are generally reliable but are aimed at less intensive drivers. Favor a model equipped with the smooth and reliable Aisin automatic gearbox, and ensure that the AdBlue system (on diesels) shows no faults during the test drive.
