The Opel Insignia B (sold as Vauxhall Insignia in the UK, Buick Regal in North America/China, and Holden Commodore ZB in Australia/NZ) is a D-segment family/executive car. Based on the GM E2XX platform, it is the last Opel model developed entirely under General Motors before the PSA/Stellantis takeover. Available as a Grand Sport (liftback), Sports Tourer (estate), and Country Tourer (raised estate), it is praised for its sleek design, excellent highway cruising capabilities, and spacious interior. A facelift was introduced in 2020, bringing updated front styling, improved matrix LED headlights, and a revised engine lineup (transitioning from GM to some PSA-influenced units, though mostly retaining GM architectures). Overall Rating: 7.5/10.
The Opel Insignia B is an underrated, highly competent long-distance cruiser. If you are looking for a petrol model, the 1.5 Turbo (140 or 165 PS) is the sweet spot: it is reliable, economical, and punchy enough for daily use, provided it has been serviced with the correct Dexos oil. Enthusiasts should be very cautious with the pre-facelift 2.0T (260 PS) due to known piston vulnerabilities; the post-2020 2.0T (200/230 PS) is a much safer bet. Avoid the 1.6 CDTI diesel unless the timing chain has already been replaced with proof. Overall, it represents fantastic value on the used market.
