Looks like a typical 420SEL, with an OK euro light upgrade, and a mixed interior. They could have tried to hide the US spec wipers.
Wood is from a 560, so are various center console bits. The rest is from a pre 85 W126, also the seats have been recoverd. Notice they look funny and over stuffed.
Think of it as a mixed breed W126. Someone lived next to a junk yard!
Might be a decent enough car for $1k.
