You have a 5.0 liter V8, named the M117 engine. Since it wasn't sold in the US, for engine stuff use a 1981-1985 500SEL, and for body stuff use a 1981 380SL. It's all the same. If you "want as much info as possible", start with reading posts in the R107 forum. Search out "500SL" in there and just start reading.
It's an uncommon car for the US, but I wouldn't say it was rare (or valuable from a rarity standpoint).
