I had a very dark green car that, like black, looked great right after I washed it, but then it always looked dirty after that and any swirl marks showed up. I got the silver IS350 and have been very happy with it for two reasons. First, it looks great even afer a week or more of dry weather and, even with a few spits of rain, it will still look good. You'll be more likely to wash it to clean the brake dust off the front wheels than because the body looks dirty. Second, it reflects heat better so it's cooler in the summer. I also agree, it shows off the lines better too. This particular shade of silver almost glows in the bright sun.
