Hi Bren,
I've got a 2009 Ford Fiesta Econetic. Its siblings are the C30 Drive, some mazdas and Peugeots.

I was looking for a C30 when a 2009 Fiesta econetic with low kays popped up for half the price so I got distracted and bought it.
Im pretty happy with it, no problems in the last 14 months 40K.
Fuel consumption wise, when 90 percent highway running it uses 4lts per 100.
Mix of town and highway pushes it up to 4.4.
I believe the C30 Drive is very similar in consumption.
