Its like asking a chef what he likes cook for himself. So what do you mean by lack of confidence? are new cars junk or just untested?
Is this specific to Ford dealers?
We see the problems, we know what it takes to fix them, and we don't want to have to deal with that stuff on our own vehicles.
My Ranger, I can have the engine out and in in just under six hours, no lift, just hand tools and a cherry picker. Time to put an engine in a newer Escape? 20 hours, with a lift and power tools. I overhaul the transmissions from the 13-19 Escapes, and replace engines in them with alarming regularity. Hardly ever did that stuff on the 01-12s.
A lot of stuff on newer cars is one time use. Nuts, bolts, trim panels. I did a sunroof shade in a 13 MKZ (Lincoln Fusion) last week, C pillar trim panels "Remove and discard".
Not just that, but the levels of system integration, nothing is stand alone anymore, and lots of the parts needed to make simple stuff work are expensive electronics that will be obsolete and discontinued in a decade or less. Right now I am working on an 18 F-150. Radio doesn't work, easy right? I am unable to do anything even remotely useful for diagnostics because the "smart data link module" which is the scan tool's connection, but also an electronic module that handles signals from the networks I need keeps dying and I don't know why.
I don't want or need air conditioning, GPS, anti-lock brakes, automatic transmissions, SYNC or other comparable connectivity technologies, or "smart data link modules". I don't need every little thing to be a freaking module, I don't want a fully integrated interdependent network of computers in my car. Guess what I can't buy a new car without.
What I do want is a manual transmission, stand-alone systems, basic vehicle with a radio that can be replaced. Guess what I can't buy.
Most of my co-workers feel the same way.
