So, after much deliberation and cost calculations we are buying a nissan leaf 24kwh leaf. 2014 with 24000 on the clock. We are replacing a 2.5year old kia picanto. Will be used as our second car mainly. Due to collect in just over a week and a half. All things being equal should save around £50a month. Although older than the picanto it feels a more substantial car and is better speccd. So won't feel like a trade down.
