If it's not yet 3 years old, the proper way to say that is "year and year"
Also, "scrapped" is a bit of a misnomer. You read part about the cars I told you went to Africa? Those are scrapped cars. In the eyes of the Western World, they enter the stats as scrapped. Of course, in reality, that's not what happens to them in Africa.
Sad to hear the quality of that car was so low. I do hear from several people that anything built after 2000 really dipped in quality.
ICE cars don't last that long on average.
However, it doesn't need to be that way. A well maintained ICE car will last you several decades. Personally I've been driving the same car for the past 21 years (405000km)
What really happens is that people get tired of their car and replace it early. The next owner is less affluent and skimps on maintenance and repairs, and the downward spiral starts for the car.
Eventually, the car gets exported to Eastern Europe(1), and then after another decade when they're done with it, it gets exported to Africa where it will run until it totally falls apart, and then will live on as spare parts.
(1) I live in Western Europe. This is the way Mercedes, Audi, and BMW take. Other brands may skip directly to Africa.
