A car is just a box in perspective. Go to the ArtWOD beginner road and work through that. That will teach you the fundamentals of form and perspective which will give you the tools to draw anything you want.

You can start the beginner road for free. Beyond that there are plenty of free online resources such as Drawabox

Can I get some feedback on a two point perspective drawing or I get feedback later
Replying to @marko20052515
Yes, when you submit a relevant drawing. Be sure to ask for what you want feedback on. Please try to be specific
Can I get some feedback on back rooms drawing or can I feedback later
