Although solid-state electronics and modules in new cars are generally reliable, the Corvette restoration community has seen the same issues with some of the Pertronix conversion modules. The bad news is that when they fail, you're dead on the side of the road, with no repair possible, and the units aren't sold in retail auto parts stores - only by mail. Although the failure rate is quite low, most who have them have learned to carry a set of points and condenser (or a spare module) and a small screwdriver in their "road box" so they aren't stranded in the middle of nowhere if the module takes a dump.
