I went for the 1.7 cdti 4x4, as i currently have an astra 1.7 sri(130). On test drive of the front wheel drive 1.7 oil burner i did notice the engine seemed a lot coarser than my astra j, but seems to have more low end grunt, probably better for suv spec as i was impressed with the launch, akin to my van (connect 1.8).
