Between the F55 and F56, is there actually any difference in the boot compartment shape? I need to retrofit a flat load boot kit, and am getting nowhere with my enquiries except one parts dealer who said his kit would only fit the R56. Is there that much difference between the F55 and F56?The kits were coded S493a when ordered as an option on a new car. They are not are not available at my UK MINI garage even if I were prepared to pay their gigantic charges. In fact the guy who answered my phone really had no idea what I was talking about. Can anyone help me out here?
