I PLAN to buy a new car to tow my 1600kg boat. I live in a hilly area. My ED Falcon six doesn't have the grunt and I've broken the auto trans twice. I have test-driven a 2004 Commodore SV6 and was impressed with the power, but I'm not sure if the drive train and chassis will be up to the job, and what the fuel consumption may be when not towing.
THE keys to keeping your auto alive are to service it regularly and not overheat it by overloading. Holden has towing packs capable of handling 1200kg, 1600kg and 2100kg for the VZ. I recommend you go for the heaviest. As for the chassis and driveline, I don't see a problem, but do get the best towing pack. I would only be guessing on the fuel consumption you might get.
