In some ways, yes. Understanding what is wrong is central to fixing modern cars, where it was often pretty obvious in older cars. Getting to things in older cars was almost always a lot easier as well.
Failure rates were higher in older cars but for each failure the repair was usually easier. The criticality of some systems, especially the cooling system and the cam timing, was generally much lower in older cars. Older cars dealt with sub-standard fuel better, but at the expense of efficiency.
Lots of tradeoffs, but I am glad not to have to fight with carburetors and Kettering ignition. I am not so glad to have to get to that thing I can barely see under the exhaust manifold, the thing that requires an expensive special tool that doesn't even fit in there. I love EPDM hoses and belts; I hate special fasteners. All in all, I love my 2002 Prius that went over 190K miles before needing its first actual repair. An afternoon to change out an electric coolant pump may not be fun but only dealing with it rarely (even the brakes are original) tickles me pink. Constant filing and adjustment of ignition points and setting timing or trying to get a carburetor to be happy with the season does not.
