Hey, congrats on the new car. I am very jelous. About keeping it clean, check out
www.calcarcover.com. They have a duster that picks up dust without scratching the paint and car covers to keep the dust off. If you watch Crank & Chrome on TNN they had a great show on auto detailing. Check out their site and
www.crankandchrome.com for more tips. The best idea is the duster, wich is quick and effective and the cover which keeps dust off and supposedly (I don't own one) breaths well so if it gets wet, water does not sit it evaporates. For such a nice car, I would try to keep it away from rain and sprinklers if possible anyway.
Hope it helps.
