Some of the longevity is based on the type of vehicle. The Honda and Toyota seem to be based on small trucks. It may not be the absolute truth but the Subaru’s seem like overweight cars to me and when they have expensive repairs when they are older, the owners may choose to junk them and start over. It seems that there are fewer truck-like vehicles in the junkyard than cars. It could be because the utility vehicles are recycled to the maximum where cars are just crushed. My reasoning may be off if a lot more caes are sold than sport-utes. In any case I think the Suzukis and the Subarus will be more problematic than the two others you listed.
