E63 Builds




I'm looking to purchase a CLS 63S within a couple months (posting on here because E63's are more common) and was just curious as to people's builds (mods/performance upgrades), and how they've been in terms of reliability (especially transmission) along with any recommendations/advice.
I would likely be doing an ECU, air intake, Fi catless-exhaust, and a clutch upgrade (Weistec or AMS not sure), and maybe upgrading the turbo.
