Pre-Owned means you pay more for the used car.
Certified Pre-Owned, means you pay for the certification that says "Yes, I certify, this is a used car. And I'm upping the price to 8,000!"
Used Car means, it's simply, a used car, and no professional, has said, or certified, it as one.

Gosh! A Car that's not new!
