In the United Kingdom, the Financial Conduct Authority (FCA), which began regulating insurance contracts in this context in 2005, found that the additional guarantees sold by car dealers are «unlikely to be insured».  Insurance coverage can provide better protection for the consumer. In the United States, various laws, including those of the Single Code of Commerce, provide tacit safeguards.  However, these unspoken guarantees have often been limited by disclaimers. In 1975, the Magnuson-Moss Warranty Act was passed to strengthen safeguards for consumer products.  Among other things, unspoken statutory guarantees cannot be excluded where an explicit guarantee is offered and legal fees may be recovered.

Factual allegations in a contract or when obtaining the contract are considered guarantees or insurance.
