It should be clear by now that BabkenBMW is trolling here for attention, and his simple point is this: Go for the Merc, drop the F10.
Check out the the comparison by Motortrend as was pointed out by another:

Quote "Our quarter-mile time of 14.1 seconds was identical, and in fact the trap speed was up from 100.6 mph to 101.0. The 60-mph-dash was a tenth slower at 5.6 seconds, while times to the higher speeds were improved (21.6 seconds to 120 mph beats the twin-turbo featherweight by six-tenths). That's impressive, especially if the fuel economy ends up equal or better."
