If you need to buy a car in Europe, buy a diesel one.

The drive towards electrical cars will push the price up of electrical cars and electricity, and incentivize governments to tax both more.

At the same time, as consumers are discouraged to buy diesel cars, you will get them cheap.

And as refineries are made to produce a certain ratio of diesel and fuel, there will be a surplus of diesel, driving it's price down.

Last bit: as neither the lithium production capacity nor the current electrical network are able to reach the 100% electrical engine target by 2035, the right to sell and use internal combustion engines will be extended.

Eventually, the right time to buy an electrical car is probably 5 years away.
