These were my thoughts when I first read this thread. Mine had only 25k miles upon purchase and it was no where near the price for that truck and yes I know the diesel gives a higher price tag. And I dont care how long a diesel can last, it's the other wearable parts on a vehicle.

If you likethe truck, but have patience, make them and offer they CAN ,yes thats can, refuse and leave it at that. If they want to sell it bad enough they'll call you.
