Future Vehicles are now able to convert your old school car in to an Electric car. One car they can convert is the old Mini. Once converted it will be able to travel up to 40mph and have a range of about 50 miles. When buying the conversion kit, Future Vehicles will source you a good quality mini, convert it and have it ready ASAP for you. Prices range from about 17500 GBP including VAT.
A Citroen 2CV is another option which converts well due to its small and light size.
