Super late reply, but the low mileage cars I mentioned were a 2011 Ford Ranger and ~2008 Ford Fusion. As far as my hypothetical ideal fleet, probably full of vehicles from Honda and Toyota. They have a strong reputation of lasting forever with just the wear and tear items.

I'm personally driving a 2010 Civic which just crossed 100k miles, and a 2009 CR-V with 140k miles. The Civic will likely be sold in the next few years pursuing an upgrade to safety while it would still have a ton of life left in it. It'll probably go to some high school kid who is learning to drive, and its end of life will more likely be due to a crash.

I just put money into the Civic for wheel bearings (likely needed because it sat most of 2020), transmission fluid, and brake fluid, and the CR-V checked out fine at its oil change. In ~75k miles, we have only done front suspension, tires, wheel alignments, oil changes, and a set of brakes on the CR-V. It spent a couple years in a town with terrible roads, which I point to as the primary reason for the suspension breaking.
