If I were buying a $90k car and you told me that $50-$100 of that went into sturdy door handles, I'd be entirely okay with that. Unless I'm buying a track car, I'm expecting the high price tag to be reasonably good parts and then the "death by a thousand cuts" of small design and engineering details meant to make a better driving/riding experience. That's the 80% of the work/cost that makes 20% of a difference.
