I would tend to disagree with that statement as a whole. Bought this car with 10,000 km on it, no improvement in almost 3 yrs...and 80,000 km.

This one was from new, just over 2 yrs...taking out the high peaks (those would be towing the camper long distanced) I'd say it remained relatively flat from 0 to 47,000+ km.

Not quite a year, but 15,000 km...

Same results here...new to 30,000 km, year and a half.

Nope...no improvement.
I call bullshi* that they get better, but not like I have the data to back it up.

If there is an improvement, it's so insignificant as to be a result of a tailwind or a downhill section of road, surely not because either one was "more" broken in.
