A more thorough explanation:

Dealer's talk is a term used to describe the exaggerated opinions expressed by a seller with the intention of selling a product or service. This is also known as puffing. Puffing involves expressing opinions rather than stating facts. It is important to note that while there is some leeway in puffing goods, a seller cannot misrepresent them or claim that they have attributes that they do not possess.

For example, a car salesman may say that a particular car is the "best on the market" or "the most reliable car you'll ever own." These statements are opinions and not necessarily factual, but they are used to persuade the buyer to make a purchase.

It is important to distinguish between puffing and factual misrepresentation. While puffing is legal, misrepresentation is not. Misrepresentation involves making false statements about a product or service with the intention of deceiving the buyer.
