I'm still averaging over 30mpg after a year (but I do 80 miles a day commuting on roads when I can't really go over 60mph with all the lorries) and my insurance is sub £400 so not that high for running costs really. Tax is £270 so only £50 more than my old Puma.
Drove over to my mums yesterday with my little'un in the car so didn't go mad - you'd not really know it was a yob if you drive it "normally" as it's comfy and quiet. But give it some beans and it rewards you with an amazing engine / exhaust note and smiles guaranteed.
A great all round car IMO.
