I bought a 2004 3.9 V6 Mustang (automatic) in early May with 67k. At least, I'm pretty sure it's one of the 3.9 models. There's a V6 sticker on the front and from what I have read, that means that it's a 3.9.
Anyways, pretty much just lurking around, trying to find out how to do some maintenance and what parts people recommend. Definitely not looking to mod it up except for probably a new headunit so I can plug my iPod in and maybe tinting the windows a bit.
