Paint to Compare
Selected cars can be painted with any of four different colors by pressing the desired color swatch button in the toolbar:
- Select the cars of interest, so that they are marked in red.
- Press any of the color swatch buttons in the toolbar.
- All the cars marked in red will be painted with that color.
- Repeat these steps for other cars or group of cars as desired...

The paint remains until it is either overpainted with a different color, or all the coloring is reset by pressing the "Reset Colors" button in the toolbar.
Because of its permanent nature, painting is well suited for comparing cars: paint a few cars with one color and then use a different color to paint the cars that you want to compare.
