You can still negotiate the best price you can get. If that is on one from a dealer offering the "Certified pre-owned" then great.

If not you can always take any used car you are interested in buying to a good mechanic and pay to have the same inspection performed.

Keep in mind that used car dealers can buy used cars the same way that new car dealers can. So the inspection can be done on any of those cars. The new car dealer calls it a "Certified pre-owned" inspection but that has no more value than an inspection from any good service tech.

If the car is only a year or two years old it's still under warranty so the inspection has less value. If something goes wrong with it, it's covered under the warranty.

Just because the new car dealer calls it a "Certified preowned" inspection doesn't mean any special inspection was actually performed. New car dealers are not all that reputable. In other words, you can't trust them.

So get any car you buy inspected if you don't know how to do it yourself.
