How about a Nissan Primera dCi. Model years '05 & up? This 5 door hatchback with a 2.2 L doesn't look big enough to haul this boat, but looking at the body lines in the Imexus pic, it's the closest thing I've found, so far...Can anyone recognize the car in Duanes picture?
edit: Further searching on this car shows a towing capacity (braked) of 1500 kg. On the (non-English) IMEXUS site, it shows a boat weight of 1480 kg, presuming this spec doesn't include trailer & motor...
