I have had the F30 320i and it wasnt bad coming from the E90 320i which was a donkey of note. Shortly after this one of the guys on the forum had a great deal on his f30 330d with only 32000kms on it, was probably one of the best cars I have owned, sold it last month. With a bit of a heavy foot consumption would be around 9-10 l/100kms, long distance cruising I got around 6. The torque on this car makes it a real treat to drive. The cost to extend plan by one year without kms is around R24k. As the guys have advised drive as many cars as you can to get a feel for them.
