Avoid low-mileage Ducatos that spend half of the year parked up on a driveway doing nothing. These vehicles will be prone to costly problems with the injectors, EGR valves and DPF.

Large diesel vans are designed to cover large mileages over seven or eight years before being scrapped. They are not designed for 2,000 or 3,000 miles a year and long periods in storage.

So what will a good used Ducato camper van look like? It will be used regularly and the owner will have a comprehensive history file for the vehicle that shows an annual service (and oil change) every 12 months or 12,000 miles (whichever comes first). If the van has gas, pay for a habitation safety check.

Listen for any knocks from the suspension when test-driving the van (this will point to wear). Also, check the tyres for uneven wear pointing to poor alignment of the suspension.
