This is a Royalty free low poly car. I suggest using it in Blender, but I have put the file in other file forms (e.g., FBX, OBJ, and STL). The color of the car can be easily changed, but the files of it are the yellow version.
BLEND (Blender, filesize: 14.8 MB), OBJ (OBJ, filesize: 14.7 MB), FBX (Autodesk FBX, filesize: 14.7 MB), STL (Stereolithography, filesize: 14.7 MB)
