We have a Mazda 6 diesel estate 2003 from new, 62k miles and tow an Oddyssey 462 (1380kg) It towed our previous van very well but now at 90% I find I am nervous over about 55 mph, this is the only reason why I am looking for something bigger. It has been very reliable, loads of power, 41mpg overall average over the 62k miles, about 45 on a solo run, about 27 towing the new van. The weak point on them seems to be the fuel pump which is very expensive, the warning signs apparently are poor starting. As I said mines been perfect. In looking for a heavier replacement I have searched the net including honest john (a good site) and it is difficult to find any car with a totally clear bill of health. The nearest to perfection seems to be the Honda CR-V but I wanted an auto this time..
