To me, long hours of comfort along with piece of mind goes away when we have 240 @ 050 durations, headers, 3.91's, Holley blue fuel pumps and full aftermarket ignitions. Hard to carry a spare for everything aftermarket on the ignition and fuel system. And who wants to listen to hours of 3k rpm's to do 55 mph ? You are correct, these cars were built pretty simple and are simply reliable. Very easy to buy replacement parts or carry a few things with you for less than 30 bucks.
