A few questions
2012e63 non PP...I am missing HP, LSD,Steering wheels and brake upgrade. I can always get a tune and get the HP back.. Install an LSD later on. Are the brakes the same and just painted calipers or better pads...The steering wheel Is cool but not a big deal...
2014..is the motor the same internals as the 2012s...
looking at the cars I love both 2012 and 2014 but the $ save from 2012 I can upgrade it to a higher level performing car than over a 2014...
coming over from 05 e55 and 07 E63...BMW 540s...

 

The brakes are the same between '12 and '14, even within the same year's PP and non PP, just different in color.

Engines (M157) are also the same, just different oem tune. Also the same M157 in SL63 and S63, but factory turned to 664 lb-ft.

 

you can also purchase the alcantara steering wheel off eBay. If you buy sell yours on ebay then you can break even or end up only costing you $100-$200.

 

the biggest different is 4 Matic or not.
You need 4wd, then 14.
If not, 12 is just as good (or better if you like RWD like some of us here)

 

Just need to match my color and options...
I also wanted to confirm that the motor are the same and the added power was from tuning.
Have a wonderful Easter everyone....
