I cheated a little here, I roughed this image in a while back for a thread on another board and I also did not take the original photo. I slammed it, chopped it from stock in the front to 3-4 inches in the rear, I shaved it, skirted it, added lakes pipes and Cadillac dagmars. I also moved the portholes to create a lower look as well as shave the upper taillights.
If I could use the program better I would paint it too
