I bought a brand new 6 speed estate TDCI last year ,and it tows my Senator Indiana a treat ,where i live in Swansea South Wales there is quite a few steep hills and there and theres no trouble pulling up them ,i average 29MPG towing and 37 around town solo , and sometimes i travel to Farnborough in Hampshire to work which is 165 miles away so i leave at 4,30 AM and when i start the journey i zero the MPG meter and as soon as i get on the M4 Motorway i keep in 6th gear as much as possible traveling at no more than 70 ,the best economy i have had is 64.8 MPG , i have tried to beat that figure since but the nearest i have come is 62
