Hello, fellow European. The starting price of electric cars is definitely the biggest issue (and there isn't a sizable second-hand market yet).
If you want to spend even less find out if you can convert your car to LPG. I have been driving with LPG for about 2 years and I couldn't be more satisfied.
According to the german Ministry for Economic Affairs and Climate Protection, there is not much difference in operating costs between an electric vehicle and a CNG/LPG vehicle. Source: PDF from June 2023
But this does not take into account the price of the vehicle as such. In this case, lpg is much cheaper.
