When they were new, the mid/late 60's GTs were pretty darn reliable, at least the drivetrain. I put 260k miles of DD going to work and back driving, plus a couple of trips around the West on my 64 Sprint GT. The only real problems I had with it were the crappy Dunlop brakes and the lower inboard front suspension bushings. The drive train and clutch just wouldn't quit. And, the body didn't rust at all.
The later 78 Alfetta was pretty darn reliable as well. We put 180k miles of DD on that car, no rust, original clutch, did not touch the drivetrain, except for a driveline rebuild, and it still lives on in Massachusetts. Yes, the 75 Alfetta did rust quickly, because I drove it in DC during a couple of winters, not here. Was actually more fun to drive than the 78. Gearing I guess.
The pristine Milano has 100k miles on it, and the drivetrain is untouched, including clutch. Has required a new rear suspension bushing, a waterpump change when new on warranty. Once again, other makers components can be considered suspect, such as Bosch electrical stuff. Always suspect in my experience through the years.
The 91S has 190k miles on it of DD, and the basic drivetrain is bulletproof, having not touched it except for the usual maintenance. Clutch untouched since the car was new, AFAICT. Other components, yes, some of those were/are unreliable, but built by other companies, such as the fuel pump and steering rack.
So, I found them to be pretty reliable, of course, not like your average Toyota I guess, but still good enough for DD plus some hot rodding, lol.
Making restored older cars as reliable is a little chancier, since it takes more money, time and effort to bring them back. Still, once the drivetrain is restored to a as new condition, I wouldn't hesitate to take it on the road for a trip or use it as a DD. The other stuff, usually made by others, electrical, whatever, is always going to be the main buggaboo. The body, it will be what it is, is the owners choice.
