Your questing from what I understand is why the dealer couldn't quote a price on a upfront extended warranty?That all has zero to do with my question.
Simple, a new car has no history once we enter into the used car market that all changes.
Everything You Should Know About Extended Car Warranties
Driving History: Some warranty providers take the vehicle owner’s own driving history into account when determining the final price. It may seem trivial, but the provider considers how well you treat your vehicle and how likely you are to get in an accident. This is common with auto insurance as well, where a good driving history can lower the cost of insurance policies.
