First there is NOT a Sun roof,or side air bags..... To me that would be a serious deduct even if YOU are not worried about it...
Be sure to check the 'in service date [if under 4 years you can get a real factory extended warranty] Car fax for sure,and have a dealer get/pull the service history to make sure it's not a problem truck...Even with that low of miles there should be at least 3 oil changes..ect...The 06 is a greater desired model true,but it should be a little lower than 28k A sorta good price for a QC but If it were me I would offer 24K..I consider a roof , Nav, communication pac [there were 2 different one's one for 300.00 or so and 1 over 500.00] REALLY important...There are always for sale a few with more miles.Take some cash with you and put it on the dash or hood..It's soooo easy to argue numbers..When some folks see the green..It makes it real.
