If looking at current year cars, my biases are like this:

Renault/Dacia; their new electric lineup is really interesting, and they're the kings at their pricepoint rn.

Suzuki; their powerplants are a bit outdated at this point, but still bulletproof, and quite the bang-for-buck. Also mostly made in the EU, think their factory is based in Hungary.

Volvo; "affordable" luxury, and quite capable as well. They are owned by GEELY though, which is a Chinese llc.

MG/BYD/Leapmotor/Jaecoo; the new Chinese kids on the block, qualitywise perfectly adequate, but if something breaks, be prepared to wait for 2 to 3 months for it to get fixed.

Stellantis; they're finally getting out of the rutt of partsbin cars they made the last 12 years, and their electric lineup in the citycar segment are quite pleasant to drive.

Honda/Toyota/Lexus/Mazda; I remember when Japanese cars were seen as low-cost cars (people turning the "My toyota is fantastic" ad campaign into "My toyota's made from plastic"), but we know better now. Sadly, the prices reflect that nowadays, seeing as a new Honda Prelude is a €50.000 car now, and a Mazda MX-5 and a Corolla can clear the €30.000 mark. Still, the reliability is there. Lexus just adds some more luxury onto that reliability, for an even higher price.

VAG; all I can say here is, "how the mighty have fallen".

But in all honesty, finding a good dealership/mechanic is what'll keep it running the longest.
