Hi MetalMickey, yes it had a full service before I bought it. Actually, my initial fears on the car's fuel economy have been completely eradicated now. Did a 200 mile trip over the weekend. There, taking the 'scenic' route, I got 54.6 MPG. Coming back (motorway), I got a whopping61 MPG. This was by driving conservatively, admittedly!
As you say, it takes a little time to get used to the extra power.
