There is no peace of mind with anything. Like what? My buddies 2006' Tacoma w/ 67k on it with a completely rusted out frame and now they are buying back his truck TBD and he has had a rental car for the past two months because they aren't sure what to do wit hit yet (Colorado Springs). I sold that truck to him 3 years ago for $12,500 with 52k on it. He has ad to replace a/c compressor, power steering pump, and an instrument dash that went south. Now, the entire fucking frame. So, I don't even entertain this one brand is better than others BS excluding Lada. I sold my 2004' Ford F-150 FX-4 with 190k on it for $5k. I had $10k in it. This was in "good" condition, full ARE topper, full thule rack, I just did the 5.4 spark plugs + boots, new BFG KO2 A/T tires with 1k on them, complete 200k maintenance myself. I did a 2600 mile road trip in it from Colorado to Indiana to Jackson hole to Denver two weeks ago. I took a $5k hit because it blue books at $5k. It was fucking awesome and would've kept it but I drive too much to justify 15mpg and live downtown so parking was always a bitch.
I have had
Ford 7.3 diesel
Ford F-150
Chevy 6.5 diesel, Duramax diesel
Dodge W250 Cummins, sold it with 330k on it
Toyota Tacoma 2006 crew cab tsp
Toyota Hilux x 2(lived in Europe for awhile)
The Ford F-150 was by far the least maintenance for the mileage. Like said, there is no GMC is shit, or Chevy sucks, it just depends on individual vehicle unless you buy a Ford Pinto
