I wonder if he has redone the seat leather in that car. The drivers is like new for 112k.
Tbh as was the drivers seat in my 728 @ 125k when I sold it. They hide miles very well.
My 728 was fine, not underpowered from behind the wheel. Yes, I wished I'd gone for a 740 in all honesty, that said, I would probably happily opt for a well specked 728 again!
The V12 is lovely if you have deep pockets, as said, the 740 is the best compromise IMO.
