Reality: Handling is HIGHLY SUBJECTIVE.
If all you had ever driven were 1970's American cars, a BMW or MB would awaken you to a whole new level of handling. Same for motorhomes.
I have worked on and done mechanical inspections on coaches I would NOT drive. Yet the owners did not know there was anything sub-standard. I am talking about things like shocks hanging from one end, bell cranks with 1" of play, etc.
So, unlike factual information, handling and ride for that matter are often subject to interpretation.
