I don't have any experience with the Meguiars Gold Class or Zaino brothers, but I've had great results with the multi-step products (Cleaner, Polish, Wax) from Meguiars. I don't know the Cleaner #, but I use their Cleaner (not cleaner wax), Polish #7, and Wax #26.
That combination works great and is how I was trained to detail cars back in college. Granted there may be better products now (~10 years later) but if that was good enough from Ferrari's, Bimmers, Benz, Jag's, etc, and did a great job, then it's good enough for my ITR.
fwiw-these products make the most impact on dark colored cars. White's and other light colors turn out good, but the blacks, dark blues, deep reds, etc have the most dramatic results.
