Pricing
The Twizy is no longer sold as a new car, although there is some good news if that makes you sad. The Twizy is going to make a comeback as the Duo, which you can read about here. The Duo will only be 'sold' through subscription packages and lease plans, so you won't be able to buy one outright.
This is because the pricing of the Twizy ultimately limited its appeal. At first it was only available with a strange scheme where you bought the 'car' but leased the battery. This proved unpopular with customers and made selling the car on the used market complex. Renault soon relented and moved to a more conventional purchase arrangement where the buyer paid outright for the battery and car together, however it made the Twizy more expensive than a budget hatchback.
New alternatives include the Citroen Ami. It's also a quadricycle with a tiny footprint, battery and price tag, offered straight from the dealership rom £7,695 - a price that certainly makes it tempting, considering it's competitive with the price of late example Twizys.
