Currently they only survive in the EU thanks to tarrifs on Chinese cars.
And I would say the opposite about Tesla, they experienced the biggest selling drop of all brands combined, if there's one brand going to crash first, I'd bet on Tesla.
The Renault 4, Renault 5 and Megan seem really competitive.
The new Nissan Leaf (made in UK) also looks pretty good.
VAG seem to have lost the plot (“let’s replace all the controls with a small, janky touch system that leaks personal information to hackers”) but their ID.7 isn’t total crap.
Comparing Renaults to the Chinese brands I’ve seen (MG and BYD) the Chinese brands were a bit cheaper but they really felt it with cheap interiors and uncomfortable seats. I’d rather pay a grand more and get a car I like.
I view all cars as depreciating liabilities and so have little interest in buy either Seal or its Mercedes equivalent.
Still, 5th is far from "eh" - on a test drive it ended up quite a nice Passat level car.
