I suspected this was an obvious question but it seems like a lot of people disagree with me. I say kilometres travelled is far more important than manufactured year. I'd rather a 10 year old car with 50,000kms than a 3 year old car with 90,000kms. Cars only age with use so the less it's been driven the better it is.
Would you agree?
The year is more important as compinent can be outdated, rusty or defect. While it's easy to say how much kilometers might matters, i saw people buying cars from japan (12 years old but really really low kilometers) and end up having to fix most parts of it.
