The sensors were defective resulting in serious problems, including uncontrolled deceleration and loss of power. The buyer suffered substantial losses as a result, including the cost of inspections and replacement of parts. It sought to argue that the contract was formed on its business terms and sought to recover its losses from the seller. The seller argued that the contract was formed on its terms and that its liability was limited to repair, in accordance with its standard terms, which the buyer had accepted by taking delivery of the sensors; while the buyer argued that the seller's liability was unlimited (in accordance with its standard terms).
So, if a letter or document that nominally or presumably conveys the signer's "intent" or intention to buy, is essentially meaningless and worthless in legal terms, and is not binding on the signer or anyone, and CANNOT be enforced on him, then why would a respectable crude buyer, in the first place, want to waste its precious time and resources (or that of its expensive lawyers) to engage in such a fruitless exercise for the benefit of a seller? Especially for an unknown or obscure seller?
