Ford will tow it without a problem and it wont f**k the Auto. I have towed many cars with fords and como's. The braked towing capacity is usally about 1600kg. If you exceed this it is illeagal. find out the recomended braked towing capacity first.
You only need to ask yourself this question. Is the cost in fuel, trailer hire and wear and tear, rachet straps and risk of damage less than getting a tow truck. If yes tow yourself. Call around and get your prices for trailer hire costs etc. Then call Jack and only Jack from City Wide towing and tell him your a member of SAU and ask for a quote for a tow, his number is 0419 877 437.
Good luck with it all.
