:) my dad's got exactly the same car, its brilliant. Sat nav is great and really usefull but we have nothing to compare it to. He often averages 50 mpg when he's driving normally. It performs really well on the odd occasion he lets me loose with it <_< and can leave quite a bit standing when the turbo kicks in Only problem has been a faulty power-steering belt that screeched when it was cold but that got sorted under warrenty. I've got his old Corolla diesel, its 8 years old and i'm still waiting for something to break. Have fun!
