A point most of those people miss, is that if these cars are that complicated to service, what does that say for assembling them? There are plenty of people right here on these forums that never miss an opportunity to denigrate (union) auto line workers as overpaid, stupid, lazy people only fit to use a screwdriver.You probably meant this as joke, but its a sad indicator of public perception.
I can assure you, any decent technician requires a very high level of reading comprehension along with a lot of other knowledge.
the days of sending the dropouts to work on cars is long gone.
