Certified pre-owned (CPO) means a used vehicle has been inspected, reconditioned, and approved by the manufacturer or dealer to meet strict quality standards. It's a used car with dealer confidence behind it.

### What you get with CPO
Every CPO vehicle passes a detailed multi-point inspection and often includes a comprehensive extended warranty covering major components. You'll receive roadside assistance, trip-interruption coverage, and sometimes special financing. Dealers stand behind CPO cars, so you have recourse if something goes wrong.

### Is it worth it?
CPO bridges new and used: you save money versus a new car but get most of the protection and peace of mind. It's ideal if you want a recent model with low-to-moderate mileage and don't want to worry about hidden problems.
