We featured this Ford Galaxie convertible a few months back when it was listed on craigslist for $9,500, but it has re-appeared on our radar on ebay with a much lowered asking price. Find this 1967 Ford Galaxie convertible with 428 CobraJet and 4spd manual transmission for sale in Joshua Tree, CA for $6,999 with no reserve on ebay. Thanks to an anonymous tipper!
The Mercedes-Benz W111 was the equivalent of an S-Class Mercedes in the mid sixties and has gained the nickname Heckflosse (German for Fintail). Technically the rear fins were called peilstege (German for sightlines) and weren't designed for aerodynamic stability, but to help the driver find the ends of the car when backing up. We would welcome such appendages in most modern sedans whose monstrously high belt lines (for "style") have turned locating the bumper into a game of bumper tag. Ironic that a modern S-Class lacks both the style and function of a classic W111. This 1966 Mercedes-Benz W111 Heckflosse is for sale in frosty Anchorage, AK via craiglist for the hot price of $5,500. Thanks for the tip from ANCMatt. 
The Mercedes-Benz W108 is a favorite of the grey-hairs in the Daily Turismo blogging collective. They are cheap, well-built and sweet looking - and we even did an entire write up on the W108 market last week. The only violation of the Daily Turismo requirements is that most of them come equipped with automatic transmissions...and it is rare to find one that might be equipped with a 4 on the floor. Find this 1970 Mercedes-Benz 280SE with what might be a 4 speed, for sale in Los Angeles, CA for $3,000 via craigslist. 
Its not every day that you can find a smokin deal on ebay - but this 1970 BMW 2002 Roundie offered in Glendora, CA for $1500 certainly qualifies as something smouldering... We think it wouldn't take $13.5k to shove a Rover V8 into the front and a coat of paint on the outside to make today's earlier BMW New Class look expensive.
We don't need to remind you how awesome the W108 Mercedes-Benz is...do we? Consider this a reminder that there was a time when the tri-point insignia was synonymous with quality, class and luxury - not the crackerjack-box-prize, latest market buzzword chasing appliances it now symbolizes. This stately 1971 Mercedes-Benz 280SE with 4-speed manual transmission is for sale in Greenville, SC and currently bidding on ebay at $3,050 reserve-not-met with 5 days to go.
