How much should I pay for this 2013 xDrive28i?

I am going to go take a look at this X3 once they complete the CPO inspection but just wanted to get some opinions on pricing. Its a 2013 xDrive28i with 20,000 miles. It was a single owner lease return. Includes Premium package, Technology package, Nevada leather, and Convenience package. They are listing it for $34,500 which would include the CPO according to the salesperson. Was wondering what you guys thought might be a fair price to offer on this car assuming it checks out and if there is anything specific issues that I should be looking for with this particular car.
