I am looking at getting an 04/05 diesel but on autotrader the specs for 1.3cdti fuel consumption are the same as the 1.7cdti however it says the 1.3 is 0-60 in 12.8 top speed 107 & the 1.7 is 14 seconds and 104??? anyone got proper fuel con/top speed/0-60 specs for both as I would have thought the 1.7 would have been quicker
