What is a fair price to buy a 2011 Ford f150 xlt supercab?

Standard options, at, 29k miles (is $22͵900 too much to pay?)

KBB shows the "private party" seller price for a 2011 F150 XLT Supercab with standard options and in excellent condition to be $23,250.

It seems like a good deal. My friend just go a 2012 for $23,000. What options does it include? Does it have SYNC?
