Well I probably shouldn't comment here as I will be the oldest I guess. 66, but definitely don't feel it and still into rock and roll etc.!
I've also got a 3.5 litre Rover classic which I've had for 34 years. My last car was a 2 litre turbo diesel and the DS4 1.6HDi is just as quick. I loved the DSport but mainly decided against it due to the lack of spare wheel as we might get a blow-out in the middle of the wilds of Scotland or France which would not be a bundle of fun with no spare and no phone signal. Once had a blow-out in a forest in the Pyrenees, but no problem as I had a spare.
