which allows:

carTable = new javax.swing.JTable();
carTable.setModel(CarTableModel.getInstance());

and displays data. While not dynamic, it at least does what I expect it
to. I think that the listeners and fire* methods will be the bigger
challenge, first I might hook it up to MySQL.

Thanks, the questions, comments and critiques helped me think it through
a better and led to approach a simpler version first.
