I get your point, but what I still do not understand is how a business should cater to a non-customer. Can you please explain that? Can you please explain how a business should spend money on someone who has not spent money on their products?
Anyone in business could care less about parties outside of their marketing mix. They would not be interested in the used product buyer because that buyer never gave their business any money, other than some ancillary benefit of better resale value allowing for a higher initial price. Sure, a strong product would speak for itself, but the best warranty is the one you never use.
I have another question to everyone then, would a warranty change your purchase decision. I mean, would you buy a Hyundai which has a huge warranty instead of a Ferrari, which only has a 1 year warranty? How important is a warranty really?
