What is the difference between an used car and a preowned car?

sometimes preowned have warranty and in better condition than used.

But still at the end, they are both used cars. Just marketing games.

Certified pre-owned cars are used cars being sold by their original manufacturer that have been inspected and are deemed safe enough to be backed by a manufacturer warranty(ex: certified preowned Mazda's have a 5yr/100,000 mile power train warranty and 8yr/100,000 free road side assistance at a mazda dealer). Now as someone said earlier their could be a Mercedes/Lexus/Ferrari/Bugatti right next to this mazda in much better condition but the manufacturer will only back their own vehicles so its just a used car. So basically certified pre-owned means you get a new manufacturer power train warranty and if its not made by the dealer that's selling it, its just used.

89 Octane sounds low, a 2006 C280 can have ping sensors, and using this slash grade gasoline will commonly no longer influence the car's reliability, however performance and gas financial system will undoubtedly undergo as these cars would've been made with octane RON phases above ninety five in intellect. You will have a premium automobile, if you want to get the first-class out of your auto be prepared to pay for the gas.

a preowned is a used car ! it means someone else owned it at 1 time !

Pre-owned cars and used cars are typically the same, but 'Certified Pre-Owned Cars' usually meet stricter quality standards.

Nothing. It's a play on words that marketers use.

It's the same thing.

SAME, no difference at all.
