Junkyard Finds: 80s High-End German IronS

During my last visit to a local self-service junkyard, I noticed far more than the usual number of expensive German cars from the 80s, mostly in non-wrecked condition. Has some threshold been reached, where such cars are no longer worth maintaining? Here's a handful of photos of an '80 633CSi ($32,825 new, $83,232 in 2007 dollars), an '84 633CSi ($40,705 new, $81,855 in 2007 dollars), and an '89 Mercedes-Benz 560SEL ($72,280 new, $121,789 in 2007 dollars). I must admit that I wondered- briefly- if that big Mercedes V8 would fit in a Crown Victoria's engine compartment.
