Haha I meant why a 65 vs a 63?
Depends on which 63 you're referring to, the newer ones from 2013-2018 i cannot afford. The older ones, from 2009-2012, that engine is too weak. It's NA and people were complaining so they brought back turbos.
I have the older V12 Turbo, but it makes 600hp/700lb ft of torque right now, so that's plenty!

Fun car to drive around esp after driving the slow land cruiser around.
However, the Benz will die long before the cruiser though, that's for sure, even though it only has 1/3 the mileage of the LC.
