Think of how much you will save for the Termi and then look at what you could do to the car you already own. A 425whp GT on the stock longblock and a supercharger with all the extra bits/pieces to get the power to the ground is likely going to cost less and is nothing to sneeze at.
Just playing devil's advocate. I still think the Terminator was the ultimate Mustang for the everyman. Near supercar power yet affordable and endlessly modifiable. The Mach is another one to look at if the Terminator is out of your price range.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
