1984 300D Turbo purchased for myself with 190K purchased for $7000 from a friend in about 1995 sold 4 years later with 286K for $4500 (needed evaporator core for $2500). Fantastic car, meticulously maintained before I purchased it and repairs during ownership were relatively minor and typical for the mark (seat pads replaced, restitched a few seams in the seat skins, shocks, oil lines, alternator, AC compressor, etc. but nothing more than $100 at a time. Wish I had kept that one.

1984 380SE purchased for myself from the family @ 90K in around 1998 for $10K, car was absolutely flawless. Typical parts for the vintage, No major expenses, sold car several years later for $6K with 150K. Hated to let it go as still a cream puff, but too many cars back then and this one developed intermittent gremlin stumble that no one could fix.

1987 300E purchased for the wife from a friend in mid 90's with 125K paid $10K, with exception of a few bizzare fuel pump/AC relay arcing episodes, car was very reliable with typical parts consumption. Sold after 4 years for $5K, car reproduced the arc a year later for the new owner (a friend) and never survived.

1992 500E - purchased in about 2000 for $20K with 90K on it, realizing that while a cosmetic cream puff, it needed a few items typical to the 500E to ensure pristine longevity (timing chains, rails, cold start racka-racka fix, pesky oil leak-just had to fix it, water pump, rebuilt the heads while in there, engine wiring harness, power steering pump, etc. putting over $10K into the car). Along with my Orange 1974 911 Carrera Targa Turbo (sold after 23 years together), the 500E will always be the automotive love of my life. While the porsche is often trying to humble you, the 500E always instills confidence.
