Tommy, try looking through EBAY listings to see if you can find something you could maybe take apart and repaint for your friend. There are loads of '53 Caddy diecasts listed there. While many are convertibles, there are a few hardtops. If your friend is serious about wanting a model of his car, he should be willing to pay for the cost of the car and shipping. Whether or not you charge him for your time, labor, and materials to take it apart, repaint and detail it is between the 2 of you. I have built several models for friends who had no problem paying for the cost of the model and the shipping. I did it as a favor to my friends, but in several cases, they paid me a little extra for my efforts. Good luck with your project.
