Buy Fiat 500e or lease?

Today I drove the Fiat 500e and was very pleased with the car. The driving behaviour has promised me and the equipment I found quite modern and chic (at least in the upscale La Prima variant). With a driving performance of approx. 10,000km annually, mainly short and medium distance in and around the big city as well as every 4-6 weeks approx. 150km highway in the home, I think to downsize. In the car are rarely more than 2 people and much trunk I do not need either. The current leasing rates are not so convincing with the Fiat 500e. With the large battery and the one or other extra equipment (winter package, LED pig launcher, PDC) it will be difficult to find something less than 250 € per month at a term of 3 years. The purchase price would settle at approx. 36k € list price. So after environmental premium approx. 27k €. Therefore, I wonder whether leasing or purchase would be more worthwhile. In order to make the lease more worthwhile, the car would have to be worth less than € 18k after 3 years after deduction of the premiums (at the time of purchase at € 27k) (about 50% of the list price). To the 27k € there may be additional interest if car is partially financed. With the current high premiums, however, I can hardly assess how the performance of e-cars is in the coming years. An advantage for the purchase would be the flexibility, which is important to me. I can well imagine I’m also more flexible about the choice of free workshops and whether I can repair minor paint damage or whether I can live with it well. Leasing on the other hand has the advantage that I’m only tied to a car for a short time. If the car doesn’t suit me in the long run, I can just do this after 3 years. Also, the industry is very fast-paced and who knows who will be able to drive the car. How far the technology has developed in terms of batteries and electric drive in a few years, or how the prices have developed up to then. My current lease runs until next year. So it is to be seen to what extent the BAFA premium is still available next year. However, this would affect both leasing and the purchase. What is your opinion on this issue? Do you have further points that I should take into account?
