Interesting topic, my Ford Ranger shop truck has 320k miles and has never seen full throttle. My Camry Wagon (dog hauler) had 270k and never saw full throttle and neither has the Equinox that replaced it. I have no interest in driving them hard because I'm the guy that'll need to fix it if they break.... Now my hobby cars are a completely opposite story. I don't mind working on those.
On a related note my brother (has a nine second 70 Firebird and an eleven second 02 Firebird) drives a concrete truck for a living. The truck developed an issue which kept breaking one of the differentials constantly. He was accused of "beating" on the truck and causing the problem because he races cars. (Obviously, full throttling a fully loaded concrete mixer is a lot of fun) Finally during the fourth or fifth repair the mechanic figured out the new ring and pinion was a different ratio than the one in the second differential.
