Is an extended warranty worth it on a 2009 Mercedes-Benz CLS-Class?
Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 6 complaints on file, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans aren't always better value.
