Here's my two cents.
If you like it, you like it. If you don't you don't. You have to choose for yourself.
Don't get caught up in the new "fad." Can you see yourself living with that color for a few years after the new mustang has lost its styling edge?
Get an interior color that you like and that you will be happy with for a while.
Red interiors in 5.0's
(Sorry if i offended someone)
There are plenty of interior pics on the internet. You should view them by yourself and make your own decision.
I don't want you stuck with an interior you're not proud of.
