I had a 14 plate Fiesta ZS TDCI 1.6 for 10 months and only got rid of it for my 15 plate Fiesta ST2, as the ZS was too slow.

Aside of that it was great. It used 2 and 1/4 tanks of fuel to get from Northern Ireland to Northern Italy via mainland UK. Which is good considering it was a 40L tank. It was averaging around 57.8MPG along that trip.
