Like I said totally not worth it. Problem is selling a 3V for decent money is very hard these days. There is a GLUT of Mustang GTs for sale not to mention all the 2011+ V6s showing up for sale now and it being a much better/newer vehicle than the 3V.
2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
