I didn't change color. I changed from Long Range to Performance. It's been blue the whole time.
I don't know if it really helped or not. I did get a new EDD that was much closer within 2 days, but I'm seeing a lot of people who have Long Range with an October order date like mine receiving their VINs now. So who knows?
No regrets though. I'm looking forward to the Performance version. I was on the fence about it when I originally ordered because of the 21" wheels, but now that overall prices have gone up on new orders it seems like a bargain comparatively, so it pushed me over. I test drove it and was fine with the feeling of the drive.
I think with color, it may help a week or two depending on what they happen to be making at the time. But at that point, you're just rolling the dice because you don't know what color is next.
