I bought an 02 Dmax dually with a lot of frills on it. Now it has 130k on it and my wife dropped many hints I should just buy a new one, just because. We have the money and a monster camper to pull which my truck pulls with no problem. I did go down and priced a replacement of the equivalent and found it to be 60K+. I paid 44K for mine originally and eventually spent money on injectors and cab corners. Stored in an air conditioned dry garage.
I have 2 people that were hounding me to buy it because it still is a very nice truck and am considering it, but I find I really like driving it. Because if this thing lasted 15 years and looks and drives so good, I imagine a new one would last till they plant me. On the other side, I would think a new truck would depreciate in 1-2 years more than the whole value of my truck, and that is why I seem to be keeping it still. It is nice riding and I don't think I would ever buy a stripped down truck. I need many of the bells and whistles to make life comfortable.
Nice to have choices like that to make !
Even with a large bank account, I'd be driving the wheels off that '02. Surprised you only have 2 people chasing that truck..... any pre-07diesel in reasonable shape usually gets huge interest, and for good reason.
If you're not aware of the "challenges" of owning a modern diesel truck, read up before you sell the 02 - otherwise you may really regret letting it go.
