I beat an SN95 V-6 Mustang in our Explorer from a 20 MPH roll a while back. Of course, this isn't a fair fight because the Explorer's 5R55E and 4.10s makes it a very surprising vehicle.
The new V-6 Mustang (2005) must be quite a bit of fun. It's the same 4.0 Cologne SOHC as the Explorer, but a lot lighter. The 3.8 Essex is a turd. The Post-99s with the split port are better, but the only V-6 Mustang I'd drive is the Cologne models.
If you are really set on an SN95 V-6, make sure it's a stick shift please. There are V-6s running 12 second 1/4s, but the Essex is a ticking time bomb to me. It also can't compare to that modular sound. Go see how the newer V-6s are. Trust me that the Cologne 4.0 would waste any Essex. I have surprised an IS300 and a 1.8T Beetle before. With a supercharger, the Cologne would be a beast.
