With the right tools, that can be simple.
First, you need an image manipulation program such as Photoshop or Paint.net. If needed, you can download free trials of said programs.
Right now, I’m using Paint.net
Once attained, open your program of choice. Click "File", Click "Open" then locate a picture of yourself. Once that picture is opened, Along the top of the window, click a button labeled "Layers" or something along those lines. Click "Import from file" or something similar. Locate & open the picture of your car. Look for a toolbox in the Paint.net window referring to Layers. You should now have a layer with the picture of you & a layer with a picture of your car. Highlight the layer with the picture of you. If you can’t see the picture of you, uncheck the checkbox next to the layer containing the car.
You should now be viewing the picture of you. Look for a toolbox in the window that contains the paint tools. Click the Lasso tool. Lasso around your body until it is completely outlined. Press ctrl+C. You have just copied the outlined image. Go to the picture of your car. Press ctrl+V. You have just pasted the picture of you onto the car image. You can now move yourself around to your desire location.
Voila! You are done!
That’s how I do it, but there’s probably a simpler way.
