Hello people! In addition to the newly bought Xc60 a little more economical should come now, and how thought, it must be a Volvo. The choice has fallen on the C30 1.6D. Now my question: Drive or not? Do you really notice the differences? Does the drive really save something noticeable, or is it just marketing? Do you possibly have the drive at home? Fuel consumption? Maybe one of the comparison I need here has already asked itself? I thank you for your answers lg praxe
