Loving the build wyzer. I think you made the right decision on sticking with the automatic. I have a 560SEC and a 300E, the W126 chassis feels very cruisey and wants to travel long distance at speed well suited for auto, my w124 is very nimble and the auto makes it feel sluggish, it’s crying out for a manual, I’ve got a Nissan CD00A 6 speed waiting to go in it.
