Is mileage or age more important when buying a used car?

I've always worked on the basis that the miles a car has done is more important than its age and have tended to choose slightly older cars with lower mileage. Having just had to get rid of a Mazda CX5 which I'm told is "old" at 12 years, I'm thinking that approach needs to change. I need the big load capacity for my building restoration project and children who keep needing help to move. Should I prioritise age (i.e. younger) over mileage?

Age and mileage are just two factors that should be considered when purchasing a used car - overall condition and service history are arguably just as important, as a younger, low mileage car with a patchy service history is not necessarily a better buy than an older car with higher mileage but that has been well maintained. Also an older car with lower mileage may have made more shorter journeys, which potentially create more wear and tear compared to a car with higher miles that has made a lot of motorway journeys.

We would suggest starting with setting a budget, and then looking at what size and bodystyle of car you require before creating a shortlist which you can then whittle down by reading our used car reviews here - www.honestjohn.co.uk/reviews/
