My van will be ten years old in early March. I have had it since new and it has just turned over 60,000 miles. I reckon it will be about 61k at ten years.
I have used it for a couple of long journeys canoeing in Scotland and one to the lakes. I also use it twice a year and drive to wash my caravan. So I reckon 90% for work.
450 a month for work.
