§ 2-313. Express Warranties by Affirmation, Promise, Description, Sample
(1) Express warranties by the seller are created as follows:
- (a) Any affirmation of fact or promise made by the seller to the buyer which relates to the goods and becomes part of the basis of the bargain creates an express warranty that the goods shall conform to the affirmation or promise.
- (b) Any description of the goods which is made part of the basis of the bargain creates an express warranty that the goods shall conform to the description.
- (c) Any sample or model which is made part of the basis of the bargain creates an express warranty that the whole of the goods shall conform to the sample or model.
(2) It is not necessary to the creation of an express warranty that the seller use formal words such as “warrant” or “guarantee” or that he have a specific intention to make a warranty, but an affirmation merely of the value of the goods or a statement purporting to be merely the seller’s opinion or commendation of the goods does not create a warranty.

Does the written auction buy/sell sheet at an auto auction supersed the “patter” of the auctioneer? This is in reference to a dealers only auction. The “green light” box is checked. Both the buyer and seller signatures are on the sheet. The auctioneer patted on about the selling dealer selling everything..as-is. There was no disclaimer as to a base price being met before the “green light” (ride&drive) kicks in.
