First, WELCOME!
As for your dilema;
I'm partial to black, having owned 2 black Camaro's.
But black is ALOT of work to maintain. If you're willing to put in the time and effort, black looks awesome when clean. But its a very unforgiving color.
Yellow will be easier to maintain. But, is it a color you will still like a few years "down the road"? I like the look of the yellow C6/ZO6, and I like 'Bumblebee' when I saw him in person, (
), but I doubt I'd ever own yellow.
Hope that helps???
