No electronics aren’t a big deal. Sometimes the clusters can get flaky.
chief issues with turbo are they’re ancient and every fitting, hose, gasket and seal is old. They quickly go from having an issue to dead engine if not promptly addressed, but their value doesn’t lend them to getting great maintenance and repair. By now most have seen bouts of poor ownership, poor oil maintenance, overheating, turbo issues....
Other than that they’re fine.
