I remember reading something online recently, about used vehicles having their least value at 10-15 years old, and after that 15 year point,IF the vehicle is in good condition it will begin to appreciate in value. As the newest 400s approach 25 years old, they're beginning to be considered "classic" or "collector" vehicles...and we've already seen the prices going up, especially on nice low mileage examples. When I bought the crew cab last year, the price was in line with Kelley blue book for that truck as equipped, at its mileage. Ten years ago we bought the Burb for $3K cash, which is what the insurance paid out on the total of the other '99 Burb it was replacing. If I was buying that truck today, with 130K on it, I would probably have to give twice that.....and if I was looking at a 2500 Burb, those seem to be really pricey.
