No formal education in Auto repair, but an Engineering degree with specialties in fluid dynamics (aerodynamics), metallurgical engineering, advanced math and physics and material design coupled with growing practical experience in heavy duty mechanics helps (although there are HUGE differences between diesel and gasoline engines).
I've often thought about taking some courses in auto mechanics. Of course I also think that good old experience is very hard to replace. Even though some guys here have no formal education in auto mechanics, they are just as, if not more knowledgeable in mustangs!
