I drive in excess of 400 miles per week and have just replaced my 2006 Fiesta Style Climate 1.4tdci (which I bought new) with a June 2007 high spec Fusion 1.6tdci +.
My Fiesta had covered 43,000 trouble free miles and averaged between 50 and 55 to the gallon. The Fusion was previously owned by Ford and has done 10,000 miles. The difference in performance and economy is staggering. The Fusion checked tankful to tankful is showing 58mpg which is much better than I ever dreamed of. The engine is much livelier and the hesitation when pulling away which I found in the Fiesta is now a thing of the past. The Fusion does feel higher geared however as I find I am having to drop down an extra gear to comfortably take some hills.
The build quality seems fine and the car is definately quieter than the Fiesta. The seats are more comfortable and the extra interior room is a bonus with elderly parents.Having paid less than £10,000 for a car still under warranty with optional metallic, reflex pack and reversing aids I am very happy.
