I do not want to make a map for my mod is about adding a car into ark so being able to craft it in a new workbench and make it driveable in game i am thinking of using the same design as dinosaurs but changing modle and texture and getting rid of the need for a saddle that way it can move around like a car i need help with this so please reply
Once we get the bigfoot in the devkit files, you can use him as a reference for not requiring a saddle. As for everything else, you are probably going to have to do alot of blueprinting, and more than likely you would be better off setting the car up as a completely independent blueprint (since it will have entirely different physics involved)
Your idea is a HUGE task, so good luck 
to be honest i will need a bit of help since i am new to this whole program so is there and begginers videos on how to do bluprinting , inserting models (from 3d max) , and how to implement the with ark etc please send me links if you know any
Most of the video links in the stickied section will help get you started with the basics, understanding blueprints, using custom models, etc… But as TheRealAzreal said, this is a huge undertaking. You will definitely need to get familiar with the blueprint system.
ok , well thanks for helping if you guys want to join me in development don’t be afraid to ask me 
In the Ark update notes they said they will releasing a drive able dune buggy to modders in the near future, my suggestion would be to wait until it comes out and work off of it as a base.
i want to tdo this mod for the contest so i want to surprise them

Ue4 Youtube car tutorial playlist:
He is using a car made with blender when importing model in first video that has defined moving wheels and define certain wheel/tire axis’s. If you are not a modeler sometimes you can find game ready vehicles with pivot points for wheels already and even opening closing hoods etc at the two i use:

Here is another video on the blender to ue4 modeling example:https://youtube.com/watch?v=6ZPPBs6NfiQ
How to modify .blend or .fbx files use:

You can also make boats and even airplanes.
I hope this helps you get started! I am working on a map now and want to work a mod with it for custom boats.
