2018 Vauxhall Insignia Tech Line Nav 2.0 Turbo Diesel Blue-injection from UK and Ireland

Summary:

Looks, performance and value

Faults:

Changed timing belt plus cam chain, expensive maintenance but worth it.

Needed new brake pads and discs.

Tyres wearing a little odd all round, maybe needs a 4 wheel alignment.

General Comments:

If you want a good looking spacious economical car, look no further than the Insignia. Very hard to beat for the money.

Tech Line Nav is a rarer spec, most are SRi models. But this car has all I need. All electrics, and very comfortable seats.

Bit of a blind spot reversing, but all modern cars are difficult to see out of, lucky I have parking sensors. It is a big car.

Start / Stop system is annoying, I always turn it off every journey.

Gorgeous in black with tinted windows. 18 inch diamond cut alloys.

At its best on long motorway drives. The 2.0 diesel is a great one. Fast and powerful. Manages around 45 mpg + but you have to take it slow. In all honesty it is a touch less economical than my old Insignia 2011 diesel model, but that was an eco-flex diesel and did around 50 mpg. But with 5 mpg less, this more modern car more than makes up for it in performance and I believe this engine will prove more reliable in the long run as I have maintained it well and so had the previous owner. Buy nothing less than a car with full history and all oil changes done.

In short, I love it.

2018 Vauxhall Insignia SRi Nav 1.5T petrol from UK and Ireland

Summary:

Perfect

Faults:

Nothing.

General Comments:

2018 Insignia Grand Sport. The perfect car if all you want is space, comfort, reliability and good running costs.

And did I mention style? My car is metallic black with tinted windows, smoked lenses, rear wiper deleted, and 18 inch diamond cut alloys. De-badged. Everyone admires this car and asks me about and they are surprised to learn it is just a run of the mill Vauxhall.

1.5T petrol engine is punchy, more reliable than the diesels, and you can get a genuine 40 mpg if you drive well.

Interior has everything you would expect in a modern car. SRi Nav is mid range spec and is a good one to go for over lesser trims. You get sports seats and pedals, lowered suspension, and more.

Put decent mileage on it in my two year ownership, mostly up and down the motorways of the UK. Reliable if serviced on time.

Conclusion: show me a better car for the money. I don't think there is one.

My thoughts exactly, though I have the 2.0 diesel on an 18 plate model. To be honest, the Insignia is a fantastic car in just about any engine and spec. But the 2017 onward model Insignia "B" is a huge improvement over the older generation.

2018 Vauxhall Insignia Elite 1.5T petrol from UK and Ireland

Summary:

My best car yet

Faults:

Air con not as efficient as it used to be.

Key fob a bit hesitant to sync up with the car, replaced batteries = problem solved.

Needed new brakes pads and front suspension ball joints at last MOT, no big deal.

In short, no major issues, just fair wear and tear expected of age and mileage.

General Comments:

Elite Insignia Grand Sport. Stunning car in black metallic.

I have the options that I need. Someone went all out in specification on this car when it was new (I am the second owner) but to my surprise the Elite is not the top spec anymore - there is an "Ultimate" model and God only knows what that has if this car seems to have everything!

The interior is very comfortable as expected. Leather easy to keep clean.

The car drives incredibly well. I miss the performance and economy of my old 2012 BMW 320d, but let me tell you this petrol Insignia is not far off. Even with the automatic box, 0-60 mph comes up in 8.5 secs. And you can get 40 mpg if you cruise slow, though 36 mpg on average is more realistic. Not great by today's standard, but for a large petrol car with an auto box, the numbers are acceptable. I avoided diesel on this car as I heard they can be troublesome engines, but the petrol's are simpler.

Tax and insurance are also reasonable. Any garage can service or repair this car as well, it is a simple Vauxhall.

In short, I'm very impressed with this car. Now why did they stop making such a fine car? I'd easily buy another.
