Had mine for 8 weeks now, never looked back, its fantastic!
Overall mpg is 44 mpg for me (not bad seeing as I only have short journeys during the week, but he gets a good run out at weekends).
Don't really pay much attention to the fuel tbh as I was just used to a tiny tank in the Lupo, the GT's tank is virtually twice the size!!

Engine is nice and quiet and the exhaust has a nice sound, being as its on a derv! And its a fantastic torquey engine with plenty of grunt through the whole rev range imo
Ride is nice and comfy too even on 18's
