Hyundai's CPO inspection process is said to be pretty good. Consider test driving it and still getting a pre-inspection from a mechanic/company that specializes in doing so. As OP said, warranty can help. Also be mindful that you'll pay a little more than the list price once you get through basic insurance cost (gap, if you would need to get an warranty extension if you weren't getting the full 100K warranty due to it being used). If you decide to go for it and test drive, recommending to be sure to take a look under the hood yourself with the salesperson as well in case their is any sign of residual fluid leaks that you'd want to ask about.
