You can still find good technicians. Usually they are the older guys who have been there for 20+ years. At my dealership(Toyota) we have 3 guys that been there 22,25,31 years and all three race Mustangs and do their own work. The younger guys are factory trained but really don't know "other" makes. Heck even when I worked for Ford, we had like 1 Tech who knew more than just todays ford engines.
Keep in mind your techs that work for a dealership won't be replacing engine parts for a 69 Mach 1. So many do not work on performance cars on the side. This is their career, not their hobby. Those that make it a hobby, you will see that they can also work on other cars and engines dealing with muscle cars and performance.
