Lisa - Can't help with the C-Max, I'm afraid. We tow with an 04 Mondeo 2.0Lx TDCi 5-door 130bhp 6-speed(this is standard on all the 130 models). As everyone says above it's an outstanding towcar - powerful, heavy, stable, reliable and economical. The engine management thing is sorted out now; it was the EGR valve, which has been re-designed. 6th gear is really an overdrive for solo fast cruising and gives you 64+ mpg; for towing you use 5th, which is the same ratio as top gear is in the old 5-speed box. We got 33mpg towing 3500 miles round Europe in the summer. I agree with Gary about the hard seats, but most people seem to find them fine. Graham
