You're looking at a Custom die cast 1/24ish scale Turtle Wagon.  It's called "the Party's Over Wagon."   It's been designed to look rusted, old, beat up and to resemble an apocalyptic universe, much like the Mad Max vehicles.  

The wagon measures, 7.5 inches long, by 4 inches wide and 5 inches tall.  All the doors open, including the gunner seat, and the rear doors as well as the roof section like in the original turtle cartoon.  This way you can look inside from the top.  To open the gunner seat there is a little handle to pull down the first door, then you can open the orange gunner door after.     This piece has been modified from the original Donatello's Party Wagon from Jada Toys.

There are many details added that you may not discover in the photos provided.  The Wagon comes with 2 turtles.  One Donnie from the original Jada set and another from the Mega blocks toys, who is fully articulated, as Donnie is not.  Both turtles have been customized and painted to fit the universe. The Smaller Mega Blocks turtle comes with a sword and a TGRI Mutagen canister.  Donnie has been equipped with a tattered Jedi robe and a calculator on his belt, as well as his signature bow/staff weapon.  Both turtles fit in the back, but were not designed to sit in the driver or passenger seats.  There is a half eaten box of Dominoes pizza in the front seat area thats also littered with soda cans.  Shredder's battered rusted helmet is also in the back on the floor as well as a TV monitor with April on the Channel 6 News.  

This is a one of a kind collectors art piece and isn't recommended as a toy, however, there are many positions and ways to display your turtles around and or in the Party's Over Wagon.  All the graffiti on the wagon is a turtles reference either from the original movie or the cartoons.  Each Turtles name is graffitied somewhere on the van.  The two guns on the top also rotate up and down.

I encourage you to visit my Insta page or my public face book page at b2botworkshop to view 90+ more photos of this piece.  There are a lot of fun variations of this item.  You won't find anything like this for sale, it is a one of a kind.  This makes for a great display piece, as it is not too large to showcase in your home or fit on the shelf with your other 1/18 or 1/24 vehicles.  Thanks for looking.  Feel free to ask any questions.
