I am now selling my much loved Twizy. Very unusually, it comes with the battery, so you will not require a battery rental agreement with Renault. The battery is almost new (replaced under warranty in January 2016).
This unique position results from the fact that when I bought it second hand, I was not informed about the need for a battery rental. Ironically, the first registered keeper was Renault UK! I am the second. Renault have cleared their interest off the HPI register (in June 2015).
If you are interested, please feel free to make contact, or ask any question. The vehicle is now for sale by auction on E-Bay, if you prefer to make contact by that route: http://www.ebay.co.uk/itm/-/272162843025?
