Okay, sorry, but your second post gave me a good laugh.
You got us excited as well, but unless you're building the 2013 Mustang on another site, the Ford site does not have the build and price function as of yet. If I'm incorrect, please let me know and provide a link.
In the meantime, keep up to date with all things Mustang via Media.Ford.com.
Well, actually, I'm still an idiot.. but there is some creative trickery going on too. There is a page www.ford.com/2013_Mustang searchable via Google that leads you to a build and price option, but if you look carefully you'll see that the link defaults back to the 2012 cars. Nice... real nice Ford.
I found what I wanted though. There's a new blue color coming and a new green color as well. The green is going to be interesting. The current Mustang color options are boring. They would have been boring in the 1980s.. that's how boring they are. White, blue, black, red, silver. Take your pick as long as it's boring. LOL. Henry Ford would be proud.. he only offered black.
