I just taxed my Sportage. £240 for the year. The previous diesels I had were £0 but I deliberately got out of that fuel type last year. It isn't as if I do many miles. They might have been "officially" low on CO2
but they were bad in other respects.
I hope that there is no snow/ice and such this year, but I have 4WD on this'un so that might be a help.
When electric cars stop looking fugly, have a 350+ mile cold weather range and charge 3% to 100% in five minutes, they might be an option. The other downer for electric is no gears. Gears are for proper drivers
Second hand electrics will likely have buggered batteries so they won't be attractive buys.
