Renault Fluence EV? Am I mad?

[oldmanbm]

My wife's current commute to work is only 5 miles return per day and we have decided to give her old Polo to eldest daughter as first car. We have two other modern vehicles but one of them is a large diesel jeep that we use for caravanning. The Polo has been great but with such a small mileage it would seem electric would be a possibility. The local Mitsubishi dealer is selling a 2013 Renault Fluence with 20 odd thousand miles for less than £4000. It's like new and represents a lot of car for the money. Has anyone experience of the Fluence? Would we be better to double to £8k and look for a nearly new Zoe or a Toyota Yaris Hybid?
