Isn’t it before electronics heavily started to get into the cars ?

Of course, we can view the car as a single purpose ‘move from A to B’ device, but there’s other viewpoints where the car has a performance (speed, efficiency, handling assist, smoother engine management) profile, quality of life and security features (auto cruising, speed limit detection, tire pressure detection, auto braking etc)

All of these should have evolved enough in 10 years that you get significant benefits from an upgrade.
