Used Saab 9-5 Aero as a caravan tow car: is there enough pulling power and does fuel consumption scare?

Moottori magazine tested a used Saab 9-5 Aero as a tow car for a caravan. In July, the car was hitched to a suitably sized caravan and taken on the road to assess its towing capability and fuel consumption. The rear of the Saab appeared to sag unusually low under the load, although the nose weight was deemed reasonable. During the trip, it became apparent that many other traditional passenger cars towing caravans also had sagging rears.
