1. What is mileage in reality

Mileage is not just the numbers on the odometer. It is a reflection of the history of operation: how many times the engine was started, how many kilometers the wheels traveled, how the suspension was loaded. Even if you replace half of the parts, you still cannot reset the car's "life counter".

2. Theoretical scenario: replace everything

Let's imagine: you change the engine, gearbox, suspension, brakes, electrics, body parts. It would seem that nothing is left of the old car. But an important point:

legally, the car still retains its VIN number;

the mileage does not disappear from the traffic police database or the accounting service;

When selling, the car will be listed with its history.

That is, formally, it is not a new car, but an old car with new "stuffing".

3. Why it will not be possible to "zero"

Documents. The body number and VIN remain the same. You can use them to find out the real age of the car.

Electronics. In modern cars, the mileage is stored not only in the odometer, but also in the control units, ABS, gearbox. It is almost impossible to simply "roll it back".

Market. Even with a complete replacement of parts, the car will be assessed by the year of manufacture and legal age.

4. And if you assemble a car from scratch?

Now that's a different case. If you take a body with a "zero" VIN (or register the car as self-assembly), then it will be a new unit of equipment. But this is so expensive and complicated that it is easier to buy a new car.

Conclusion

It is impossible to reset the mileage by replacing all the parts. The history of the car is tied to its VIN number and documents. Yes, technically the car may be like new, but legally it will always remain with its past. Therefore, the idea of ​​"assembling a new car from an old one" is more fantasy than a real possibility.
