All of the 400's were auto. Not planning on swapping anything in the near future but if I were to swap I imagine a stick shift is going to happen.
The interior is meh, I got a bunch of cracked pieces but nothing major. The pick and pull has replacements I just don't want to pony up yet.
Drives like a dream guys. The way the car landed on me is awesome. It is my brothers dream car after all. He wants the 300 with the 2jz swap though. Me, I prefer the v8 anyway. It is one of te most reliable motors ever anyway.
My daughters love it. They think it is a bit cramped but otherwise it is very smooth.
