For the most part that car should clean up rather well. The ledge with clear coat failure about half way up the bumper, and the roof where the white stuff is near the rubber window trim likely won't be improved much because the white stuff is typically moisture and oxidation trapped between the separated clear coat and the base coat paint. You can buff those two areas all you want and you'll never touch the white stuff because it's trapped under the remaining clear coat.
The hood and the rest of the car look to be just topical oxidation and should clean up well. If I had to choose products from off the shelf, I'd go to Advance Auto Parts and go to the body repair section (where they stock the Bondo and other body repair stuff) and grab a quart of M-105 and use it with a white polishing pad on your G 110 following Kevin Brown's "Supplemental Wetting Agents" Method. If you're not familiar with "the method", just google it and give it a quick read. That should clean the car up well enough for some average Joe to think the car looks spectacular, other than the clear coat issues. Follow the 105 step with some NXT 2.0 and you'll be in business.
Remember, the perspective buyer won't likely have a discriminating eye like us detailers do, so why horse around trying to impress us? It's pretty easy to impress the average car guy.
