It entirely depends on what kind of mileage and what kind of time. 100tkm in city traffic only could easily be more devastating than 500tkm on highway. (Or some similar-ish proportion.) Conversely, time spent in controlled storage, with appropriate precautions taken before and after, doesn&#x27;t necessarily count much. Yet time spent in active use even with low mileage (say, a single one-stretch 100 km trip per week) will wear out parts and components. Changes in temperature and humidity have an effect there. I&#x27;ve also observed common replacement cycles mostly regardless to mileage for some parts: a ten-year car is likely to need similar parts replaced regardless of whether it has 100tkm or 250tkm on it. Some parts are more worn by miles, some parts more by time in active use.
