Sooo, as I understand and see this is a prototype/start of project?
Not Bad, neither good! U gotta fix the sound. When the car starts the sound is ok until the car goes to idle there is slight miss pitch in the sounds, and there is some sound over lapping when you drive. Good textures, if we close our eyes bout the sound problem it's good!
Overall 7.5/10!
Suggestion: Add settings like graphics/audio(could be only the tabs) :)
