1) In the case of Ferrari, the cost of ownership is relative to not only the cost of the car, but also the quality of the product, since most of the parts are designed not only to work in the real world, but to be able to run at capacity levels (so anywhere between 186 to 215 mph, depending on the model) on a track weekend, and then back to the real world when Monday comes around. Just because the owner doesn't take the car to the track doesn't mean that the parts will not wear out as fast as if the car was tracked, because the parts are designed more with performance and flexibility in use than longevity.
Obviously an F22 which doesn't see combat will need more replacement parts over its life span than a commercial jet. Its parts, like a Ferrari's are designed for a different purpose in mind.
2) Some things, especially high-performance and almost-artisan mechanical items (watches, for instance) are oftentimes wasted on their owners. Take zjpj, he truly is a Ferrari connoisseur, and fully appreciates his car for more than just its performance and its name brand and the showing that it "˜entitles' the owner. His F430 isn't wasted on him because he appreciates the car, in all its aspects. And while an owner doesn't need to be as knowledgeable as he is, he must like zjpj have true respect for the item, an appreciation FOR the item, not just what it represents to the world. Unfortunately, most owners purchase their Ferrari's for one reason, and one reason only: to show off.
