Old trucks (and cars) are simple, analog, easy to work on and troubleshoot. New cars are full of crap like “Body Control Modules” and “Anti-lock brake controllers” Shit that cost a ton of money to do something that is mostly un-needed.
I'm toying with the idea of getting a Classic daily-driver from the 60's or 70's. For the most part, I don't drive a lot. If I buy an old truck, in 10 years, I will still have an “old truck”. Might even be worth more than I pay for it or not, but it won't be 10's of thousands of dollars less because it's a new-fangled car that looses money by the second.
