Bob, new cars have a purpose - to provide transportation needs to people who do not want, nor wish to own old cars. Not everyone (thankfully) likes old cars and trucks. One big advantage to a new vehicle is a warranty - an a pretty damn good one, too! The disadvantages are - they are NOT designed in any way to be worked on by the owner. Not even so much as a damn oil change on many of them. Plus, a basic car with few options is going to cost $15K. I can buy a pretty damn nice old car or truck for that and have change in my pocket.
I rented a '12 Nissan Sentra to drive on a trip to Colorado recently, and put 2,450 miles on it. Got 37 mpg for a trip average, too! Pretty impressive, but would I go buy a new Sentra? No. When I need to do a road trip, I'll happily spend $300 to rent someone elses car and put the wear and tear on IT and not my vehicles. The new cars are good for what they are designed to do - haul people around. Will people restore 2014 Mustangs and Challengers forty years from now? The answer is "yes", but they'd better be very well-versed in today's electronics, because with an average of eight separate computers in new vehicles, there is a LOT to go wrong. You think finding a working LeanBurn computer is bad? At least, a guy can easily work around a failed LB and bypass it. Nothing in today's cars is designed to be bypassed, or even repaired! Most warranty work is remove the old and replace with new. No "repair" work is done.
So, yes, I'll continue to drive my 28-year-old Ford wagon on a daily basis. And at $3.75/gallon @ 17 mpg, I'm still spending FAR less than the guy who just bought a 2014 Whatever, with his high car payment, insurance, 35 mpg, and overall cost-per-mile. Oh, and the eight to 20 airbags to spontaneously deploy, and then total an otherwise-undamaged vehicle. Pass.
And, there is NO way I can justify spending $40K on a Mustang, Challenger, or a Camaro (and that is not even the top-end cars!), nor the same on a mid-level half-ton gas pickup. Insanity rules these days.
