Worth pointing out that for very low mileage users many cars struggle to get over 30mpg as the engine/gearbox fluids do not get up to temperature. I’ve been running a petrol Qashqai cvt for nearly 3 years, and on a decent run it has done 45mpg, but most days it’s around 28, especially in cold weather.
I’ve shortlisted 2 cars that were very different. Just ordered XC40 over bmw i3 despite similar ap and obvious fuel cost. Worth paying for the fuel in my opinion.
