There will be an element of competition between dealers, but have you contacted any of them to see if the vehicles are actually for sale?
When I bought my 22MY Ocean earlier this year in Germany, I'd say more than half of the adverts were for vans that were not available - either old adverts, vans that were already reserved or sold, dealers fishing for orders, and a fair number which were EU re-imports. The devil is in the detail, check the options lists for the vans for sale, just 2-tone paint can add almost 4K to the price.
