At least 3000kg gvw, but 3300 would be better imo. Transit 330 springs to mind, and from looking on autotrader and ebay recently there seems to be quite a few around (must have been some large nationwide company replacing their fleet?). They are front wheel drive swb semi high roof versions, in silver with the 110ps 2.2 engine (not the 2.4 you get in the rear wheel drive ones) and 6 speed box. mileages vary from about 55k upwards, and prices seem to start at around £6.5k.
