You'll be fine buying a 17 with that low of miles. It will be certified pre owned since Ford is selling it. My 17 EL XLT 202a was a fleet lease that came out of Los Angeles and then to a Ford only dealer auction in Seattle. I bought it with 33k certified pre owned and now have 38k without a squeek or rattle and it tows like a beast (I even added ecobeast door badges for giggles). I signed the papers without even driving it. The dealer had 3 identical ones to choose from and mine had the best condition interior but it was in dealer prep getting new brakes and tires at the time I got to see it. You'll still have a couple thousand miles of bumper to bumper warranty if anything comes up, and then the 12k comprehensive from Ford cpo plus the 7yr 100k miles (from date of new purchase) powertrain warranty with just a $100 deductible.
