yeah, That's exactly what I did.
The neighbors probably thought I was crazy.
I took a pic of the car with the camera on the tripod, left it there, move the car few feet away and took another pic
Then just superimpose the 2 pics in gimp.
The light was slightly different I couldn't get the color hue to match exactly, hence why the final pic is using this tone.
I then just use the eraser to let the background show up.
I wanted to open all the windows, so it would show the inside of the car, but I forgot. I did this in a hurry, less than 15min.
