I'm consideting parting with my S w212 with 40k miles as I'm hunting for an s213 e63s. 2 owners including me, comprehensive maintenance schedule , iPE valvetronic exhaust (gbp4.4k) fitted by msl, 360 camera , night pack, panoramic roof etc etc bigger breaks than standard, lsd, intelligent led adaptive lights , brand new battery. Aftermarket android auto and Apple CarPlay. Auto watch ghost, front and rear dashcam thinkware f800 pro.
Totally stock, dynoed while doing exhaust by msl with 630 hp and 840nm torque using their 1.18 drivetrain loss multiplier. Always get van drivers talking about the car when stuck in traffic on the motorway next to them.
