It all depends on the type of look you are going for and what you want to spend
I would get myself a porter cable 7424 and the zaino kit if you are looking for a nice high gloss shine if you are a carnuba guy I would get some
souveran wax nothing beats that or some quality wax
everyone likes a diff look, I would go to click and brag and look at some cars with diff products and see what you like.
I had a 04 G35 great car, love the 07s
