I drive a 1 year old Astra TDI van on a daily basis. It has exactly the same engine as my brothers VXR lookalike CDTi and yes it's quite nippy, fast in some areas. But i'm a pertrol head, high revs, growly engines, not 4500rpm and yer out and the classic soundtrack of Massey Fergusson ! There are ways to achieve more than 20mpg average and still have blinding performance. Unfortunatly it wont wear an MG badge but more importantly it wont be a ruddy diesel !
