Today's vehicles aren't that bad. The manufacturers just make them look intimidating. Yes there's more to deal with. Which in turn takes more time. But overall it's the same drive trains. I worked a few junk yards. You would be surprised how fast I could strip a vehicle. And I know there are better guys out there, that are way faster than me. Now when you have a issue it does take longer to diagnose the problem due to the electronics, relays, modules & sensors. And dealing with the tighter areas you have to work with really sucks. The biggest downfall to these new vehicles is the wiring just keeps getting thinner & thinner. Due to all the extras people need these days. Heat is a real killer on the wiring. It gets brittle.
