20 Road tax! Just squeaks in on lowest rate as registered 15 march 3017. This is our 30kwh family Nissan leaf Tekna (heated leather seats, heated steering wheel, 360 degrees reversing camera). It's been a fantastic car, but we've got larger one (another electric nissan!). Its just had a fresh MOT, battery has 10/12 health. In the summer, it does about 100 miles to a full charge, in the winter, more like 80 - that's how it goes with electric! It does about 4 miles per kWh, if you charge it up on a home night rate (like we do) for 9p per kWh, that's 2.5p per mile! SO19
