Here's the sad but honest truth: even if you have the best-manufactured, most reliable car on the planet, someday it's going to break down. Modern cars are complicated. And even a relatively minor defect or a mechanical breakdown can cost a fortune to repair. By purchasing a warranty, you protect the investment you made in your vehicle. In many cases, an extended warranty can pay for itself in one repair. And just having a quality, transferable warranty in place can raise the resale value of your car.
