Vauxhall Insignia Grand Sport (2017-2021) Pros and Cons

Pros	Cons
Keenly priced on the used market	Not at all sporty to drive
Economical diesels ideal for motorway driving	The Country Tourer isn't necessarily four-wheel drive
Well equipped whichever model you choose	A Skoda Superb is much more spacious

Quick Summary

The Vauxhall Insignia Grand Sport (2017-2021) is a D-segment saloon that competes with the Ford Mondeo and Volkswagen Passat. Despite its saloon appearance, it's actually a five-door hatchback with a full-opening tailgate. Available as a five-door Grand Sport, a traditional estate (Sports Tourer), or a jacked-up Country Tourer variant, the Insignia offers a massive range of options. Engine choices span from a 1.6-litre diesel with 109bhp to a potent 207bhp twin-turbo diesel in the GSi model, with several petrol alternatives in between. The 1.5-litre petrol with 163bhp offers an excellent balance of performance, torque, and fuel economy.

Practicality is a strong suit, with a 490-litre boot expanding to 1,450 litres with rear seats folded, plus optional 40:20:40 split-folding rear seats. Economical diesels achieve around 55mpg, whilst the 1.5-litre petrol manages approximately 45mpg. Most models feature timing chains, reducing maintenance costs, though 2.0-litre diesels require timing belt changes every six years or 100,000 miles. As a used purchase, the Insignia represents excellent value with abundant availability and significant depreciation benefits. However, it lacks the sportiness of dedicated driver's cars and the spaciousness of the Skoda Superb.

Best for: Budget-conscious buyers seeking a spacious, well-equipped family saloon or estate; those prioritising motorway comfort and diesel efficiency; and company car users.

Not ideal for: Drivers seeking sporty handling or premium badge appeal; buyers requiring maximum interior space; or those wanting four-wheel drive as standard on the Country Tourer.


Comparison vs Key Rivals



The Verdict

You should buy the Insignia Grand Sport if: You're seeking a spacious, well-equipped family saloon or estate on a budget, prioritising motorway comfort and diesel efficiency, or looking for excellent used value with abundant availability.

Consider alternatives if: You require sporty handling, premium badge appeal, maximum interior space, or four-wheel drive as standard on the Country Tourer.

Competitive Position: The Vauxhall Insignia Grand Sport is a solid, sensible, and dependable family choice offering excellent value and abundant equipment for the money. Whilst it won't excite with sporty driving dynamics or match the Skoda Superb's spaciousness, its keen pricing, economical diesels, and well-equipped specification make it absolutely worthy of consideration against the Ford Mondeo and Volkswagen Passat. Savage depreciation in this segment makes it a second-hand bargain, though the Skoda Superb remains its biggest competitor, trumping it in most areas.
