Faults:

Clutch, oil leak, coolant leak, exhaust, etc.

General Comments:

The Insignia is a fantastic to drive car in this range. I bought it used and put serious mileage on it. Had quite a lot of wear and tear parts fail, but the car in general was reliable if looked after.

SRi Nav trim is nice, you get sporty seats and plenty of electrics. Sat Nav built in is a bit dated, but can be retro fitted with an update.

Really good looking car in black. Nicer to drive, slick gear change and good handling on SRi models.

The engine is pretty mediocre. 1.8 petrol is fast enough if pushed, but miles per gallon suffers easily, spirited driving and short/town drives sees the MPG drop to only 32 mpg or less! You need to get out on the motorway and select 6th gear and cruise for many miles just to see 37 - 38 MPG; much better but hard to maintain. I'd have went for a diesel CDTi Insignia but was advised they were not very reliable, but at least they can manage 45 - 50 MPG; you will never get near that out of petrol. The Insignia is a heavy car and is at home on motorways, do not buy any of them if you only do short drives.

Have since moved on to a BMW 3 series which is a better car in every way, but the Insignia for the money provides a great family/executive car for anyone.

Faults:

A lot of maintenance work, new cam-belt + water pump and so on.

Brake discs and pads.

Exhaust and suspension components as required per MOT.

Coolant leak.

ABS sensor.

Difficulty selecting gears.

Low oil pressure - Oil pick up seal failed and seized engine.

General Comments:

This Insignia, although a basic "Exlcusiv" model, was a really nice looking and comfortable performing car over the time I had it.

2.0 CDTi engine was fast and economical. Great to drive. Engine a bit noisy around town, but a quiet refined cruiser on the motorway doing anything between 50 - 60 mpg.

Very comfortable interior, nice seats and plenty of kit as standard. Rear headroom a little limited if you are 6 foot or more, but otherwise no complaints.

Plenty of space in that boot. Practical car.

It's a shame the engine failed after a well known problem with the oil seal/pick up valve; do check this when buying high mileage diesel Insignia's, they are a known weak spot. I decided to scrap the car as it was higher mileage and older and not worth repairing, gearbox was feeling and sounding dodgy also. Shame really, it was a fantastic car otherwise all the time I had it. I do not know if I'd buy another - I think Vauxhall really dropped the ball here with the Insignia, they really could have had a Ford Mondeo beater if they just put a bit more effort into quality and reliability, and this could have been the perfect car, but in all honesty the Ford Mondeo is still the better car on reliability alone.

Faults:

Coolant leaks, thermostat, suspension, gearbox whine, clutch, and the air con does not work.

General Comments:

White 2012 Insignia. Really nice looking car. Bigger 18 inch SRi alloy wheels, the car looks amazing. If it had an Audi or BMW badge on it, people would notice it more.

SRi is the spec to have, very nice seats and sharp suspension, and never sacrifices ride quality, except on the roughest of surfaces. Noise suppression is also pretty good.

Performance and economy from this 1.8 petrol engine is pretty poor. I get mid 30's mpg along with lackluster performance. Go for the diesels with more horse power, or the later turbo charged 1.4 petrol.

There is a reason people always say find a trusted independent garage for servicing and repairs - for one you will keep costs down, and two you do not have to go to Vauxhall with a car this age, they are usually pretty uninterested and expensive anyway.

Overall I really like this car, it just annoys me that it could have been so much better. Do not pay too much for a used one and keep an eye out for its common faults and you should be OK.
