The kit (pickup or hardtop) runs $40 for the stl files (or straight g-code if you print on Prusa) and it comes with a pretty thorough 110 page build guide. One great thing about this particular vehicle is that there are LOADS of free and for-purchase add/mod .stls all of the interwebs for it.
You will need A LOT of 2 and 3M screws, and bearings, and the build guide tells you exactly what you need. You can certainly source these yourself, or the easy route is to go to www.rcprinter.com and order a kit specifically for your vehicle. A screw kit runs about $35+sh, and screws and bearings about $63+sh. By my math, I will need about 405 fasteners, and 38 bearings, so about $75 shipped isn't all that bad for the simplicity of one stop shopping. Quick note, rcprinter is out of Canada, so figure in shipping time.
You will also need a couple of belts for the gearbox if you go that route, some shocks, some standard 1.9 tires, motor and electronics.
Couple of Pros off the bat.
Everything is split up to print on a standard 200x200mm bed, so a huge printer isn't needed. Note: I did have one "plate" of parts that was a little bigger than my bed settings, but I could have cheated those a little if I wanted.
No added supports needed. They have supposedly tested this out left right up down, and any support needed is already on the parts. So no guessing.
There are two versions of a transmissions to run: gear or belt drive.
The diffs can be made either open or locked. I am going to run locked in the rear and open up front.
Up front ................ the number 1 thing you have to have with this build is patience! And this is not my thing, but I am getting used to it, slowly. Depending on the complexity of the "plate" you are printing at the time, and your particular settings, each print is 12-40+ hours for the major components.
I am trying to set up my prints to maximize a 24 hour print, so I can remove parts, and start again, once a day. My first group of parts. Enough to start building the chassis. Please forgive the sloppiness on the rear fenderwells and floor.
That is left over aquanet from not cleaning the bed in a LONG time. I am cleaning it well between all prints moving forward. 
The fenders printed vertically, so they supported the arch, and to remove it literally took channel locks, and left a pretty rough edge that had to be worked a bit. They also put support around the gas cap area, and in the process of removing that, mini screwdriver slipped and scratched the body. But not printing those bad boys again!
