Any price you were quoted would obviously be based on whether you were trading it in against a newer vehicle or simply selling as a private cash sale.
Although its a diesel the mileage at 274,000 km (170,000 miles) is still very high and from my own personal experience of Importing/Buying and Selling Vehicles to the Motor Trade and Public in Cyprus I would put a simple private cash sale value on it of between 800/1200 euros if you would like to match it up with other Citroen Berlingo vans that are currently for sale here in Cyprus just click on the link below,also bare in mind most Cypriots are still mindset and work in old CYP£'s and what would be the euro equivalent in their eyes meaning some second hand vehicle values are on another planet and will sit for an eternity before some mug buys them,thats why you see so many empty shops,houses and flats etc maybe one day the penny might drop but i doubt it very much!
