I dont know but perhaps selling the flat and buying a house with the money you would have spent on either of the two cars would have been wiser? Or showing status is more important around that part of europe?
They're expensive by US standards too. They'd only not be expensive by Silicon Valley standards. A Porsche Taycan is a $100k+ car. Very few people own that in the US. Most of the Teslas sold are also expensive cars by US standards too (very few are buying at base price).
And let's not forget that a whole society living in single housing is a lot less eco-friendly than someone living in an apartment in a dense city and being able to do a lot of errands walking. Transportation emissions is not the only eco-impact, there's a lot that goes into housing and non efficient use of land.
