One would assume taxi companies etc would be willing to pay for cars that have high uptime and reliability. But I think they drive mostly the same stuff as regular people. At least one would assume they could get beefier suspension and transmission and high displacement downtuned engines.
In general new cars are still vastly better than old ones. 90:s cars rusted from everywhere after ~8 years while most cars nowadays have zinc coating and more plastic and are still mostly fine after 15 years.
In your part of the world, maybe. I live in the middle of the salt belt in the US and we get about 10 years out of most cars. That's when you start seeing rust holes in the fenders around the wheels, when most of the frame has flaked away and the floor pans become involuntary structural elements.
If you're a car nut who spends extra time and money on preventive maintenance and rustproofing, you can get a few more years. But the rust comes for your car at some point anyway.
Car manufacturers know how to make the frames and bodies last longer, this is not an unsolvable manufacturing and design challenge. It's just that nobody is getting a raise for going to their boss and saying, "I know how to make the company sell slightly fewer cars..."
Rustproofing is still a good treatment to get done to delay and minimize damage, but it's a thorough and slightly expensive job.
People who have a hobby car usually retire it in a garage from November to April-May instead.
Here in the UK until recently it was all Skoda Octavias, nice simple comfortable cars with a reliable diesel engine. Prior to that, it was all Citroën Xantias - again, nice simple comfortable (really comfortable with their hydraulic suspension) cars with a big reliable diesel engine.
It's not uncommon to see them hit well over half a million miles, often in less than five years.
Only downside is the flimsy high efficiency tires, I've spent more money on tows and tires than I saved on gas.
To top that all off, in parts of CA electricity is now 50c/kWh, which makes it roughly equally expensive to charge an EV as it is to buy a tank of gas.
I love electric cars, but there is a gap between what they COULD be and what they are.
It's trending up to $0.90-1.00/kWh in places now.
Also, I no longer consider any EU car brands at all. I think they wasted all their prior brand value and now buying them is simply not a smart decision.
