phill dont tell me you are thinking of getting rid of ya collie mate??? I know the new ones have more grunt but are they as good as what we have ? Time will tell! I love my collie, 8 litres/100 round town and down to 6.8 litres on the great open road. Bet the new ones cant beat that and mine is an auto as well. When I tow my work trailer full of paint and crap I drop down to 10 litres /100. As you say the isuzu donks have proven them selves.
