The only problem with "only 650 hp) for 1.5 million dollars is well you could just buy a regular 640 that A. looks better and had more thought put into its design then the scribbling down from a designer with a hangover on a paper napkin. B. Cost a lot less than the over rated "LIMITED EDITION" with the same HP. However if its true what you say about gearing having an impact (which I doubt), but then again I havent read about it. Then reason A still stands .
