Ok even as a master BMW tech we don’t get to see all the option on a BMW ,,,,this is the rear trunk space on a F10,,,,when I saw it. I thought it was a Hybrid 5 series,,,,boy was I wrong. Yes it is,,,,I know you can’t believe it,,,,maybe some of you young guys have seen one of these,,,,lol,,,,,yes that is a spare tire donut ,,,,this car came without run flats tires,,,,we don’t see that anymore,,,,must have been a special order,,,,your trunk space is a lot smaller with the spare tire,,,,you know what I forgot to look for the car jack,,,,lol,,,,I wonder where that was,,,,or does anyone know how to use one anymore.
