More modern means more computer. Ford influence means standardized parts but built to a (lower) cost. Newer car means less aging and wear.
An automatic S would likely have lead an easier life than an R wagon but that's just a generalization. Why I say that is, I remember the JD Power surveys of the 80s, when full sized Chevys, Olsmobiles and Buicks were all the same vehicles (except for badging) but JD Power rated them in the opposite order for safety and reliability. I found that strange since they were mechanically identical BUT the type of person who bought a Buick was essentially a more cautious, older buyer when compared to a person buying the same, less expensive car from Chevrolet. Their reliability and safety was based on the demographic of the owner.
Anything with a service history and warranty would be best. With computerization, a Volvo dealer should be able to pull up any warranty work performed from the VIN number.
