It would appear to make sense to have a pure electric as a second car. Many households have two cars and where the second is used for short journeys it would appear to make practical / economic sense - running cost wise.
There are good financial arguments for NOT buying an expensive car. The interesting thing is that most people set a budget for buying a car - whether new or second-hand. If your budget stretches to £11,600 you can buy a brand new Dacia or a 10 year old RX 450h. After the purchase it is just running costs (including depreciation and reliability).
So if you had £11,600 to spend (cash!) on a SECOND car, what would you buy?
