My LS 460 just turned a year old. I have about 7,000 miles and use it as my daily driver. The exterior still has a great swirl-free finish and the interior is holding up to the abuse of a 4 year old in the back.
Exterior:
ONR wash every 2 weeks with a MF and grit guard. I sometimes use QD strength of ONR to wipe off dust between washes.
I clay with Clay Magic every 6 mos to remove contaminants.
I use Optimum Opt-Seal every 6 mos as my base and top with Optimum Car Wax (OCW) every few months.
Never had to polish this car and don't have any swirls yet
I use Optimum Opti-bond for the tires.
Here are some pics I took today after an ONR wash and after application of OCW about 7 weeks ago and is due for another coat of OCW.

I like the wet reflective look of Opti-seal and OCW. I have tried Zaino and Jeff's W, but I like the results of Opti-Seal and OCW better on my silver car.
