Hi, We have just sold our Nissan Mistral 2.7 TD Auto, which was ok to tow our 1200kg eldiss caravan on a straight road, but when it came to any kind of incline, it was rubbish, despite holding it in gear, so, we are looking to replace it with a volvo V70 estate, 2.4 petrol, the car has 170 bhp, the question is, Which will be best, auto or manual version? as we no longer want to be embarrased when HGV's overtake us on hills!! thanks in advance, Michael.
