against purchasing extended warranties unless they can be purchased at manufacturers cost. David Butler of the Consumers Union says, "The extended warranty is definitely in the best interest of the company because if the product breaks down they want you to be satisfied with it and buy another one when the time comes, but isn't often in the best interest of the consumer unless it can be purchased at cost with no or very little markup." Consumers Union said in 2006 that only two products deserved extended warranty consideration: projection TVs and digital cameras, as both are expensive to repair and require frequent repairs. In spite of such advice, consumers frequently purchase extended warranties because they overestimate the frequency of failure. Extended auto warranty All new cars in the United States come with a warranty that cover repairs for a certain period of time and a certain number of miles, such as 3 years and 36,000 miles. An extended warranty provides similar coverage beyond those time or mileage limits. Legally, only the original manufacturer can "extend" a warranty. Other providers often use the term "extended warranty" to refer to similar products, although technically they should be considered Vehicle Service Contracts rather than "warranties." According to the Automobile Protection Association (APA), which publishes the Lemon-Aid Car Buyer’s Guides, extended warranties or vehicle service contracts are a good idea if they cover items likely to break down within the coverage period. Extended auto warranties often offer other perks not included in a general factory warranty, such as trip interruption insurance and roadside assistance. Auto warranties generally do not cover vandalism or theft, dings or dents, road salt damage, environmental or natural disaster-related damage, car wash damage, or normal routine maintenance. Most vehicle service contracts are sold at car dealerships at the time the vehicle is sold, although other providers offer them outside the dealership, often at lower prices.

This guarantee survives even when
