Yeah, the challengers are the worst of the big three's retro cars, at least as far as any and all performance testing/comparisons... And the X5M/// is at least half a second quicker in 1/4 mile.
Come January we are getting one of the new Fo1/Fo2 760i/il at the dealer... 600hp twin turbo V12!!!! Taking the throne as the fastest production BMW to date!
