Hi, we recently moved to Carlow and are currently driving an 04 Focus 1.4, we want to trade up soon and were wondering should we go for a Diesel Focus as my partner has to travel to Dublin 4 nights a week for work and when I ran a search on AAM ppl seemed to recommend the 1.6Tdci if you were doing enough mileage, so I was wondering how much mileage would you need to be doing to make the diesel more economical? Thanks in advance!
