The new stuff may be trouble free now, but once "today's" technology gets some age to it, I myself will trust the old simpler vehicles hands down.
You can put a set of points or an extra ECU, and even a voltage regulator in your glove box, and change them in 5 minutes on the side of the road.
There is less to go wrong with simpler parts, like mechanical vs. electric fuel pumps, and you're not going to be changing a fuel pump that is inside your fuel tank on an offramp. You don't need a rollback and a scanner for $500 each occurrance to diagnose the old stuff.
A standard Mopar ECU is $40, and any of the body, engine, or transmission modules for anything in the last 10 years are likely in the $300-$400 range. A loose crimp on a fuelpump relay plug will not put you dead on the side of the road with our old cars, because they don't have one.
