4 cons: No safety features of any kind / No disc brakes / Terrible gas mileage / How long will a 41 + year old truck hold up while being driven daily?

I owned the same '65 F100 from March 1965 thru November 2009. It was driven daily for 3 years, then I bought a succession of new trucks thru 2006 (1968/71/79/88/92/04/06), each one better than the last.

I kept the '65, used it mainly as a chase vehicle for Rod Runs on weekends.
