Suburban Auctions?

I have decided that I want a Suburban someday, for towing, winter beater use, trips to the home center, etc. What I want specifically is this:

I like the simple headlights of this model and the lack of bling wheels. Must have tinted windows, the rest of the Secret Service stuff I do not need. 2500 and a Diesel would be ideal if they offered such a thing.

Does Uncle Sam auction these off somewhere?

Should be what you need.

Edit for correct link...

I could waste a LOT of time on that site...

I am not sure if the prices are great (at the end of the auctions) but the equipment is cool.
