I don't think any modern vehicles will achieve the longevity of older vehicles simply because they have more and complex systems.  The more electronic (auto start/stop) and mechanical (AFM, VVT) junk added to cars, the shorter their life will be.  When there is more to go wrong, it will.

Modern cars are filled to the brim with planned obsolescence, the way everything is built there's almost no way to keep the majority of them on the road for longer than 10 years or so. Just about everybody can learn how to change spark plugs, fuel injectors, and brake pads. But not everyone can learn how to fix computers, software, and security systems. 

One example I have of earlier planned obsolescence is in my 1993 Olds, I one point when I was driving it I got off the highway and the car began to shutter and shake like mad when I got under 30 MPH and quickly put itself into failsafe mode, shut off and stopped, right on a freeway exit ramp.

While I had no idea what the problem was, it continued to happen whenever I drove at freeway speeds and slowed down, it was my only car at the time and was becoming a safety issue so I had to figure out what it was and fix it.

At first I thought it could be an issue with the transmission or computer, but then after some deeper digging I came across the knowledge that this car along with it's similar counterpart the Buick Century had a "clutch solenoid" which I learned lots of owners had unplugged or taken out when it stopped working for this exact reason alone, and when I did this the problem went away completely like it never happened. Sure, I sacrificed a bit fuel milage and the "check engine" light comes on often, but that was it.

Then I thought about it a bit, and I realized how many people they must've tricked into having their transmissions "serviced or replaced" When the clutch solenoid went out of these cars, these were reliable, well made, and great vehicles. But GM had to put in something that would stop working, and make the driver think it's the transmission that is going out so some money could given to the dealerships at the time, while there's an easy fix you can do by merely unplugging a cable in the engine bay.

This is just one of the earlier examples of planned obsolescence, it started with smaller things like the smoke control systems in the late 70s and worked it's way into cars more and more since then, it's now at the point where 50 different things can go wrong in a car, the majority of which people cannot fix on their own.

The more gadgets and gizmos get put into the new cars, the shorter of a life span they will have, just based on the fact like everything else the gadgets and gizmos with the lesser quality will age and stop functioning, and the owner will have to either replace and repair thousands of dollars in the cars functionality, or get a new/used car. And when everything new is so expensive which option do you think they're going to chose?

You can attempt to keep a newer car forever, but you better have a very, VERY big bank account.

It used to be you would have labels in the car to replace air bags once every 10 to 15 years. Modern vehicles, however, do not require airbag replacement no matter how long you own the vehicle (assuming they have not been deployed). 

Is it possible to keep the car indefinitely? Yes. But you need a deep wallet so you have the ability to cover major repairs.

I recommend keeping up with the maintenance and repairs as long as it is worth doing so. 

Some cars can last 200K miles, 300K miles, or more miles on just basic maintenance. Others have a tough time getting to 100K without putting major money down.
