This is pretty much my feeling too, but selling privately. I honestly think a dealer will give me less than $5k for it.
If I decide to sell, I'll get a thorough detailing and list it for $6500 locally and see what happens.
I'm just thankful I bought it used at a good price to begin with. Between the recession, gas prices and the poor resell value, there is no way I could ever buy a brand new Titan since I tend to change trucks every 5 years.
