Why spend 8500 euros converting a C1 /Aygo/ Pug ( a bullet proof car and ideally suited to short journeys tbh) when you can get a perfectly good Nissan Leaf that will do the job, and they are super reliable and even the worst will still have a 70-80 mile range. There are a few Mercedes B classes around -not sure of price and the old pug/mitsubishi electric cars too if you want to dig around. But for the money you cannot beat the C1, Peugeot / Aygo-the 3 cylinder engine is great and they drive really nicely. Rediculously cheap to run.
