I've just returned from a 12 day trip to Bergerac, France in the above car only because I wanted to keep the miles off the RR.
You will all hate me but... It was a pleasure to drive, I never worried about it starting first time, it was smooth, comfortable and very fuel efficient. I liked it, liked it a lot.
BUT it ain't no Range Rover. I would have it as a second car though. just my personal obs.

I think you should have 50 lashes and say 100 Hail Mary's

Had one of those also as a hired car in Spain , thought it was a really good car as you say comfy and smooth ....  ====================================

"Open Mike Night " sounded like a lot of fun until i found out i was going to an Autopsy

I'm still keeping the RR but it was roomy. One for the missus I think.

we used to have a Vauxhall omega estate. 2.0 it was a very nice drive. but it was just a tin can. but a quiet one.

I think that a lot of the medium sized cars like the Insignia are good. In recent months through work I have driven hire cars to and from sites and they include an Insignia, a Volvo v40, a Mondeo, Infinity Q20 and last week a ford focus. All 1.6/2.2 diesels (I think) and all a great little drive ! Not sure how I'd live with them in fairness for grinding out Mway miles in comfort with good economy, I'd 100% agree with you the Insignia is a nice car. Is this where I put the car details and a bit about myself ?........

I drive one every day - at work. Not a bad car to be honest. 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

I thought when we hired one they seamed claustrophobic

I have hired Insignias on a few occasions,have to say,I find them very good.

I had one as a courtesy car for a week... I thought it was the nastiest car I had driven in years.
From memory it handled like a pig. I have had 6 astras and a zafira as company cars for over 20 years, so I know my vauxhalls... Last month I even bought myself a brand spanking new Vauxhall Vivaro doublecab van for my own personal use, so I am not anti-Vauxhall at all...
Anyway, I still remember to this day that the insignia is a stinker of a motor vehicle. Previously..

I've just had a week in Italy in a Fiat Panda. Great for the twisty, narrow roads there but not sure if I will p/ex the FF for a 4x4 version. 2019 Range Rover P400e

Hateful things! the one and only one id driven was donny to heywood and back and it no matter how i adjusted the seat i couldnt get it right. Left my back and thighs aching for a day or two after.

After that Avis reverted back to Jetta/Passat's for me and then a Disco4 HSE for 3 months  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

I've had a couple of 1.8 petrols as hire cars to drive from Aberdeen to home and TBH they couldn't pull the skin off a rice pudding. They do a 1.6 as well! I found the view through the rear window to be restrictive. The last of the Cavaliers were great with the 1.8 petrol, 5 up, motoring along no bother at all! Vectras were awful. Previous cars:
S-Max 2007-2013 (only diesel I've had, good car but expensive when diesely bits go wrong, so what's the point?)
Galaxy 2001-2007
Mondeo Estate 1997-2001
Sierra Estate 1993-1997
Uno Turbo 1987 -1993
Fiesta 1984 - 1987
Fiat 127 1982 - 1984

I hire cars regularly for business trips and was unlucky enough to be given an Insignia once. It was utterly ! Uncomfortable, woeful handling and complete lack of power. Must be a contender for the worst car I've ever driven.

The next time the hire company arrived with an Insignia I told them to take it back and swap it for something else.
