Hi I had the same problem with 320i ,when was the handover time i sign all paperwork then we went to see the car i a noticed straight away idrive6 so i didnt collect the car because when i order a car i asked sales man if its idrive 7 and if its not then i want to cancel the order and he confirm that in email saying idrive7, and I am waiting for new car again they reordered with compensation as follow £600 off of A/P
