Well you've seen the other pictures already but here's mine anyway:

What surprised me is that whilst the boot is huge (excuse the suitcase, wife's hospital bag for impending birth of 2nd child!), the space for the rear seats when I have the drivers seat in my driving position is somewhat lacking.
Gave a lift to a few mates the other day and had to drive with my knees touching the bottom of the dash so that they could fit in the rear seats.
However, the new sync 2 system is a million leagues ahead of the old system. Much more intuitive and the size of the screen is much more fitting for the size of the car.
As for the quality of the interior, I'd say that the materials aren't any different, but they do seem better put together and more solid, and also having less buttons in the middle of the dash makes it much cleaner looking.
As for the drive, it has a lot more mid range shove than the fiesta, but off the line it's hard to notice a difference mainly because it likes to spin the wheels without much throttle input!
I would say that it does feel more planted at high speed compared to the fiesta, but the fiesta was way more fun at lower speeds.
Also, the 35mpg I am Averaging in the pictures was from the 90 mile run between Swindon and halesowen. Mostly sat at 75mph in cruise with some foot down to get onto the motorways and overtake occasionally.
