Certified pre-owned (CPO) is a used car that's passed a manufacturer-backed or dealer inspection-not just any used vehicle. It means someone expert has verified the car is reliable.

**What CPO includes:**
- Multi-point safety and mechanical inspection
- Manufacturer or dealer warranty (details vary)
- Vehicle history report
- Roadside assistance (often)
- Sometimes financing specials or coverage add-ons

**Why it matters:**
You get the savings of a used car-no steep depreciation-with assurance that major systems are sound. It's ideal if you want lower cost than new but less risk than a random private used car.
