The first time I hand washed this car I came into the house exhausted. "Man! That thing has more planes and angles than I can count!" It felt that way. My mini van was a box: this car is a collection of concept surfaces intersecting all over the place. But I got used to it quickly.
Hand washing turned into a breeze once I locked down a machinelike method: same steps, same movements, same tools: approach it like an exercise routine, step one, and proceed to the final step.
As far as getting dirty quicker goes: not particularly. The rear end collects dust from driving a lot faster than the rest of the car. Our roads are fairly clean, so the brake side
vents don't deposit a noticeable amount of accumulation; or, I haven't noticed that at least.
It sounds like you're disliking dust accumulation. A
California Duster is the tool to keep in the hatch at all times. (I know, AV8R said his duster made his glass oily; but that could be the difference between dusters, because I never see that happen with the duster I use: "Pacific Coast Car Duster"; available through Walmart, but I got mine at O'Reilly's.)
