Even Guram in the race against the K8-Strasse RS6 comments "there is always some black magic from this owner". It does one 10.8s run and then never comes close. On the Russian BMW forum they all question how the car can do a 10.8s run and then be consistently 0.5s slower  . |
And this has been my point...I have been racing for several decades - and one constant is almost always true - owners lie about their cars. This is why you need 3rd party testing and reviews. I know you don't like it (REALLY don't like it) - but the F90 M5 is slightly quicker and faster than the E63S. The CP will be more so.
