Interesting topic! Yeah, I think driving a manual transmission is similar to owning a mechanical watch in terms of wanting to interface with a machine to a greater degree than the status quo. Do you prefer to row your own gears and wind your own watch (or just appreciate the tiny little engine working away on your wrist)? Yes! There's a historic link between mechanical watches and motorsport as well, and I think that adds to the connection.
All of my cars have manual transmissions, mostly by choice. Daily driver is a 2002 VW TDI Golf owned from new. Manual transmission bested the auto by 5-7 mpg thanks to a tall 5th gear on the manual and a slightly less aggressive fuel pump which is why I got it. Oh, and it was cheaper to buy also. I'll stick to cars that are running right now. The other manual is another German Diesel, a 1980 w123 240D 4-speed. This was the only way to get a manual w123 in the US unless you imported your own. This car doesn't really care what gear it's in, and not because it's a stump puller, but because it's 62hp (when new)! Love that it's a base model...manual windows, no sunroof, no cassette, no passenger mirror.
