Can I buy an extended warranty after I buy the car?

Usually, yes. Many automaker service contracts can be purchased any time before the factory warranty expires, and third-party contracts are often available later too, though price and eligibility may change with age and mileage. That means you do not have to decide under pressure in the finance office. Take the contract details home, compare quotes, and check reviews of the company backing it. Be wary of unsolicited calls or mail claiming your warranty is about to expire.
