I was keen to get one as our second car (small-ish run around mainly for DH to do his 25 min commute every week day - we have a larger family car).
My main reasons were the savings on running costs and the benefit to the environment. I figured we could spend 6-8k on the car and then we would save massively on petrol costs. However, taking to the men at our local garage has put me off- they said that electricity costs are almost as much as petrol and repairs on electric cars require specialist mechanics and can be massively more expensive especially when something goes wrong with the battery. They also said that the estimated remaining mileage is often more than you actually have left and you can easily run out of charge and need to stop for over an hour to charge up. The cost of buying a hybrid is putting me off that option too.
So aibu to keep my petrol car at the cost of the environment? Any positive electric car experiences?
