On the van, Mark's father-in-law bought it new in 1996 and gave it to him a few years ago as a shop van.

Graveyard Carz
To clear the air: Anyone who takes the time to research Graveyard Carz and The Division Productions knows that I started this dream with a lot of heart but not much money. I am proud of the fact that I, along with all of the Ghouls and the entire team at Division productions have managed to make a show that can compete on national television with what we have... We are of humble means and work hard. My father in law gave us this van a couple of years ago to help us out. He bought it new in 1996 and used it daily in his drywall business until he retired. It's a great old rig. 1 ton, extended, low miles and free. We use it every day here and we are happy to have her. In a perfect world we would buy a nice late model Dodge Van or a Sprinter, but for now our limited resources are best used making one great Graveyard Carz episode at a time. I just thought you should know. ~Mark
On the Challenger, I can't say for sure but they pretty much only do factory correct restorations, so I assume (yes, ASS U ME) that it came with them. Remember, back then you could get pretty much any combination of parts and trim that you wanted.
