I once looked at a Ford F150, and when I asked the guy who owned it how often he changed the oil, his response was, I never have
My second Dakota apparently was like that. I bought it as a "Certified Used Auto"... the dealer really blindsided me with that. Apparently the previous owner had run it dry on antifreeze, put in stop leak and traded. The dealer put lipstick They did replace the radiator but told me it was normal for the transmission to slip when going into 3rd gear.

The ticking which started in the engine was just the fuel injection....it was my first time without a carburetor so I didn't know any better.
The "Certification" came with some fancy paperwork so when they wouldn't fix it I called the toll free number... which referred me back to the dealer. In hindsight I should have contacted a lawyer but was working 7 days/week and putting on a thpusand miles.
I babied the transmission about 24,000 miles before it failed. The engine lasted a year before the timing chain failed, taking out the top half of the engine. I had it fixed but should have dropped a used engine instead.
I paid $7500 for it and ran it for a year and a half- spending that much again in repairs. At the time I could have bought a brand new extended cab 4wd Ranger for that price. If I had to leave town I would call the garage first to make sure somebody had time to run the wrecker if I broke down.
When I finally traded, the garage stopped opening on Saturday mornings. It was coincidence, but over the 18 month period that I had that truck I averaged 4 hours of labor there a week... not counting the work I did myself.
1 set of front spyder gears, 2 brand new-not rebuilt- Dodge transmissions ( the first had a faulty pump) 2 fuel pumps, top half of the engine.
The engine and first transmission were from lack of preventive maintenance which the dealer hid.
