Under federal law, "a written warranty" (also called an express warranty) is any written promise made in connection with the sale of a consumer product by a supplier
to a consumer that relates to the material and/or workmanship and that affirms that the product is defect-free or will meet a certain standard of performance over a specified time.
Also under federal law, "a consumer" is a buyer of consumer goods for personal use and
a buyer of consumer products for resale is not a consumer.
Sounds like the Magnuson-Moss Act says that if Superformance offers a warranty, it can only be in connection with the sale of their product to you, the consumer, not the dealer.
