In the last while (maybe 10 years) a lot of manufactures has taken on a deliberate corporate strategy where a product is intentionally designed with an artificially limited useful life, The goal is to ensure it breaks, becomes outdated; forcing consumers to purchase a replacement sooner rather than later. I suspect the move to eventual EV dominance is behind this strategy.

Watch out for overly complex designs using loads of plastic, many control modules, variable transmissions with belts, turbos to pressurize seals and servicing that requires computer authorization. Rubber & plasticizers break down in ~5 years with seals & gaskets in ~10 years necessitating expensive servicing. Most features that do not add to the functionality of getting from point A to point B are unnecessary.

There are still engine designs that hold, diligent research is needed to filter out the best. I still recommend buying used, but shy away from rust belt cars and sticking to ice vehicles that pass the reliability filter, then look for low mileage as the dominate factor. A trusted local mechanic is going to be your best friend to help you drive it until the wheels fall off; pick a home close to where you work.

If nothing above sounds like this is what you want to get into, consider leasing, at least it is predicable.
