I have a Ford Falcon Futura AU series II station wagon(estate car). It will be 12 months old in a couple of weeks. It is 5 metres (16'5") long and weighs over 1 1/2 tons. It has a 4.0 litre SOHC inline six engine with EFI and produces 157kW (210hp). It is very comfortable with room for 5 adults and an enormous boot (trunk). Being a brand new car it also very reliable and well equipped. The only downside, apart from being a Ford, is that it is very thirsty. When I'm towing on the open highway I only get 7 km/litre (20mpg). It's a good thing, I don't pay for fuel.
Marcus, my dad used to have an XF sedan with a carbied 4.1 and we towed my race car to Warwick with it and it went OK. It was so slow but it got there alright, no worries at all in fact.
