I agree. Mileage first. Then as ubervic said,negotiate. And if you are not in a hurry research more. You might be able to get a better deal if you look at autotrader etc. In my experience, autotrader and Cars.com are the best online shopping tools. If you can determine, try to find how long it has been sitting at the dealership. I would look at the KBB trade in value and use that as a starting point. The longer it is sitting there the more motivated the dealer is.
My own example, In 2010 I was able to find a 2009 Yukon XL SLT (leather DVD etc) with only 9500 miles for 30K. I researched for 3 months. I found it in Utah and I am in Los Angeles. Negotiated over the phone, flew to Salt Lake the next day and drove iot back home. My cost of acquistion was about $400, including flight and gas. It was a CA SUV in Utah, 2WD and was sitting on the lot for 6 months. And yes it has a clean title. Comprable ones in LA were about 42K to 45K at the time.
Just my thought.
