How much would you pay for this truck?

The truck is a 2006 purchased mid 2005, it is a Nissan Titan 5.6L SE and was purchased brand new. The truck is going on 3 years old and only has 18,440mi on it, it has an after market custom billet grill, flow master exhaust (cat back, 2” pipe with a 3” tip, very loud) and after market ION off-road black on chrome rims.

The interior is near perfect with only a little “wear and tare” near the steering wheel controls, and next to the shifter, speaking of which is has full stereo controls on the steering wheel, 6 disc in dash CD player, after market Rockford Fosgate component speakers ($400), automatic control captain’s chair (drive side only). It is also the model with the shifter instead of the steering wheel shift (see photo below). The exterior of the truck is kept in almost mint condition, I wash and wax the car twice a month there are a few little tiny scratches and one super small ding on the passenger door (parking structures…what can you do?).
The truck also comes with back-up censors on the rear bumper it has a temperature gauge inside the truck which also tells you which direction you are heading.

Kelly Blue Book tells me the truck is worth only $14k which I think is a little low considering at going on 3 years old it only has the miles of a 1 year old car and has been kept in extremely good condition, not to mention all of the after market enhancements. I currently owe $25k (bad credit at the time) I think the truck is worth about….18 - 22?

If you were a car dealership, considering the condition my car is in, what would you give me for a trade-in if I was willing to purchase a car from you? Or would you buy this sort of truck private party? If so, what would you be willing to pay? I’m not trying to sell it here, but I’m trying to get an idea of what I maybe COULD sell it for in the near future.

Thanks as always,

Your friend Dom.

One thing dude nissan titans are bad ass but that year 2006 has a bad reputation of breaking, trucks are meant to offroad so unless your going to use it too drive around town ur golden but if you want to offroad and jump around your going to have to put a new suspension! But for atitan at 20,000 dollars is extremely cheap if I were u I will buy it and invest a couple dollars and buy a better sudpension! (Most likely a lift!)
