My 08 Titanium model has a dimmer control, don't know if the feature was droppedon the zetec model. Ford make little spec changes on a regular basis, even the low washer fluid warning was removed from the spec list just before I ordered mine.
Minehas a 1.8 flexi-fuel engine, the petrol performance is the same as the standard 1.8. When brand new at worst I got 22mpg for short trips, stop/start driving, now average about 33mpg after 4500miles. Best was 43mpg on a 280 mile trip, about 70mph, four people, full boot and roof box. Overall the average combined figure is about 33mpg or 27mpg when using biofuel (E85). So it will get better but expect higher figures on a straight run or cruising at motorway speeds.
