I thought the F54 was to be on a platform more like the R60 rather than the F56 with its longer length & a longer wheelbase?? Since the F55 will only be about 2 inches longer than the F56, I assume it'll have the same wheelbase. Would guess that the F55 will probably be priced around 1.5K (in $) more than the F56.
Is the F56 now reaching dealers over there in Britain/Euro market yet? Have yet to hear when they'll get here in the U.S. other than 'sometime' in April! We 'still' don't have 'official' mileage figure posted here from MINIUSA. Looking forward to seeing the F56 closely in the flesh, so I can get a better idea about the F55 due out this fall. That may likely be my next one to replace my current JCWCoupe...more practical for me in my everyday driving.
