M189...same engine as in the Gullwing, which translates to $$$$$ for nearly everything about it. And the W112 300SE is indeed a rare gem, but will need a six-figure commitment for everything to be restored to concours standards (if that's the aspiration). Other than that, it will still take tens of thousands for the entire car to be properly & correctly revived. On that note, how much is the seller asking??
