Welcome...enjoy all the threads on here, but take some with a pinch of salt! What colour did you go for and as you like the hi-fi, did you go for the Premium Sound? I am disappointed if I don't get 700 miles out of a tank and six months on, love the car!

Around town, we get about 500 to a tank and it seems to average around 50-51mpg. When I use it for work, which is 99% 60mph a-road cruising, it easily hits 700 miles out of a tank, if not more. I've never driven a full tank on my own for work, but I have filled it up then gone to work and by the time I've got back home again, the total of miles driven and miles remaining in the tank is in excess of 700. Very impressed with that, our old 2.0DTi Zafira barely managed 400-450 to a tank on the same run and I think it had a slightly larger fuel tank too!
