Zoopy,
To put my Simpson character in I used Gimpshop. It is a port of the opensource graphics editor GIMP. Gimpshop attempts to make the look and feel of GIMP more like Photoshop.

Then after downloading the avatar I opened it in Gimpshop.
After selecting my character, I copied him to the clipboard.
I opened my photo of the car in Gimpshop.
I created a new layer on top of the original photo and pasted my character in that layer.
I moved around the character until I got his head in the right spot.
Then, I erased all the parts of my character that should appear to be hidden by parts of the car.
I flattened the layers of the image and exported it as a JPG so I could upload it here.
Lensvision, yes if only General Motors would return to the exciting shapes and lines of the old classics maybe they wouldn't be having such terrible trouble selling their cars today.
Real pretty example of a real pretty car. The 289 V8 introduced in '55 was indeed a great advance (especially the fuel injected version which came along in '67), over the straight 6. However, brakes and suspension left much to be desired. And, of course, like most cars of the day, these were very prone to body rot. G
