Used Vauxhall Insignia Buying Guide
The Vauxhall Insignia offers a huge amount of car for the money on the used market. The first generation ran from 2008 to 2017, but most buyers today will be looking at the second-generation Grand Sport hatchback and Sports Tourer estate sold from 2017 to 2022 — a big, refined motorway cruiser that was a fleet staple in its day. Depreciation has been brutal, which is bad news for first owners and excellent news for used buyers: few cars deliver this much space, refinement and equipment at mainstream-hatchback prices.
Engines and trims
The second-generation petrol range spans 1.5-litre and later 1.4-litre turbos through to a punchy 2.0-litre turbo, while diesels — the volume sellers — include the 1.6 CDTi “Whisper” and stronger 2.0 CDTi units. The 1.5 Turbo petrol suits mixed use, but for the Insignia’s natural habitat of long motorway hauls, a 2.0 CDTi is hard to argue against. The GSi flagship added performance, adaptive dampers and, on some versions, all-wheel drive, which also featured on selected mainstream variants. Manuals and automatics are both plentiful.
Trims moved through Design, SRi, Tech Line (another fleet favourite, usually with navigation) and Elite, with GS Line and Ultimate appearing after the 2020 facelift. Elite and Ultimate cars can include the excellent IntelliLux LED matrix headlights, worth actively seeking out, and the optional FlexRide adaptive suspension noticeably improves ride quality on bigger wheels.
What to check before buying
Because so many Insignias lived as company cars, history matters more than mileage. A high-mile motorway diesel with stamps everywhere is often a better bet than a low-mile car used for short trips, where the diesel particulate filter and EGR valve can clog — look for warning lights, hesitant running or evidence of repeated forced regenerations. On big-wheeled SRi and GSi cars, check tyres for uneven wear and listen for knocks from tired suspension bushes and drop links, as UK roads punish the larger alloys.
Inside, test the touchscreen, digital displays and every electronic convenience feature; infotainment freezes and sensor gremlins are the most commonly reported irritations. Confirm both keys are present, check the air conditioning blows properly cold, and on automatics feel for smooth, prompt shifts. Cosmetically, inspect the long doors and bumpers for car-park damage — these are wide cars — and make sure any towing history is matched by appropriate servicing.
Running costs
Diesel Insignias tend to be genuinely economical, with the 1.6 CDTi capable of impressive figures on a run and even the 2.0 CDTi returning strong motorway economy; petrols trade some efficiency for refinement. Insurance groups are reasonable for such a large car, generally undercutting premium-badged executive rivals, though GSi models sit higher. Servicing and parts benefit from Vauxhall’s enormous UK network and cheap independent specialist support. Tyres for the larger wheel sizes are the main consumable to budget for, and diesel buyers should factor occasional long runs into their usage to keep the DPF happy.
Verdict
The Insignia is one of the used market’s great bargains: enormous, comfortable, well-equipped and cheap to buy, with only badge image and resale value counting against it. Buy a well-documented diesel for big miles or a 1.5 petrol for mixed use, avoid neglected short-trip cars, and it makes a hugely sensible alternative to paying twice as much for a German badge.
