Construction costs are currently skyrocketing

Can you please invite me right away, here stands a gable roof 160m2, W-E orientation, 25-degree roof pitch unused

... because it is not being replaced.

Can I have one of the cars, please? ;-)

Besides, those who really have to commute long distances now either have an electric car or haven’t done the math yet. Selling the 2001 Fiesta and leasing a new, small electric car for 150 euros saves more per year than keeping the clunker.

So the 99-euro leasing offers I find always have a 10,000 or even 7,500 km limit. "Really long commuting," let’s say 50 to 60 km one way, rounds up to 25 to 30 thousand km with some leisure driving. And then we are talking about a 250 euro leasing rate for a small electric car.

Apples and oranges. First, I never said €99. Second: Anyone who puts 30,000 km on the road per year doesn’t drive one of the mentioned "free" 2001 Fiestas. With an electric car, however, that person saves €1500 in energy costs alone. €2500 with photovoltaics. The more you drive, the more worthwhile an electric car becomes. And those who really drive a lot, buy one. But hey: I’m not trying to convince anyone. Then the delivery times will only get longer. Anyone with a calculator should do the math themselves and then choose what’s appropriate.

Taxes, fuel, repairs, replacement of the car and very often even insurance is cheaper. That's MORE than enough, if you calculate honestly.

In my experience, that's not true. Our Twingo is now 100 months old, cost 8300,- and is now worth about 4000, which would give a leasing rate of around 40 per month, the electric car would always be over 200.
We only drive about 8000 km per year, since she works locally and I don’t work anymore at all and do most things by bike. It was different before, of course, then we had two cars. Today, if we need more than the Twingo because of a trip, we go to the ADAC rental car portal.
But that's another matter and cannot be applied to working people or commuters, who by the way commute because of homeland, because of affordable houses up here, because of a partner who works here, etc., etc. Without a flat rate, the housing situation in cities worsened even more.
But… why should one actually get rid of the Twingo, Fiesta, etc. and lease the ID3? Why? Climate protection! But the Twingo, Fiesta, etc. would still be driven, just no longer here. Elsewhere, however, and for a long time yet. So what does the electric car bring? It was not produced climate-neutrally and comes on top, mostly so far as a second car. It would really make a difference to give up one's car completely, at the moment completely unrealistic in the countryside, possibly conceivable in Hamburg. Maybe Apple will soon be at the point where you can order a Siri car on demand via an app for an annual flat rate, autonomous, Siri, drive me to Aldi, then to the harbor and to the hairdresser. If that works, it would be doable for us, my wife and me.
The bus is no alternative for me, I don’t like having to travel with a mask on graffiti-covered seats in the company of rowdy youths.

I see no connection between my quote and your text. Of course buying is always cheaper than leasing. And of course no one should throw away their car. Especially not now, when the demand for E-cars probably won’t be met for many months to years. And why do you want to upgrade directly to the compact class with the E-car? And what are you suddenly doing on the bus?!
