You should take the time and the effort to read and understand exactly what is covered and what is not covered under the warranty. You should also understand whether it is the dealer's or the manufacturer's duty to make any repairs covered by the warranty. Understand that an extended service contract is not a warranty. Both a warranty and a service contract may require someone to repair problems with the car, but they are not the same. An extended service contract is a separate contract and is sold for an additional price.
Implied warranties apply to the sale by law.
The warranty of title says that the dealer or manufacturer has good title to the car and can transfer this title to the buyer. This warranty also says that the car does not have any liens that the buyer has not been told about. Under the implied warranty of merchantability the dealer or manufacturer warrants that the car is fit for the ordinary purposes for which cars are used, that it is fit for highway driving. Minor problems, such as a broken automatic door lock, may not be considered as a breach of this warranty. Under the implied warranty of fitness for a particular purpose, the dealer or manufacturer warrants that the car is fit for a specialized purpose.
