**New cars** come with a full manufacturer warranty, the latest technology, and zero miles-but cost more. **Used vehicles** are cheaper and depreciate more slowly after you buy them, but may have unknown history and fewer warranty miles remaining. **Certified pre-owned (CPO)** is a middle ground: dealer-inspected used cars backed by extended warranties and the dealer's confidence.

### How to choose
Buy new if you want peace of mind, the newest features, and plan to keep the car long-term. Choose used if budget is tight and you're comfortable with a vehicle's existing mileage and condition. Pick CPO if you want recent-model reliability with used-car savings and extra protection.
