hey everyone please help I’m trying to make my own game I need help in modeling a car from stretch to make my own game anyone please??
i would recomend you to do it yourself so you can truely call it Your Game 
to begin with, just start off by adding a cube, and two sylinders to represent your car. you can model it later if you want.
or if you REALLY REALLY want an actuall model that you didnt make, feel free to check out Blendswap
I would advise you to start small and go big afterwards…
Anyway, this is a great tutorial for modeling a car :
“Create a car in blender with cycles” by Rob Tuytel
After that you’ll need to rig it and animate it : search for
