Tom,
See if you can get a few digital pictures of it to post. That would help those of greater knowledge to give you a better ballpark figure. The only way for you to be sure of what your getting into is to have someone (like Pat Mical at http://www.patsauto.com/) inspect it in person with you. Even if you were to spend 10k on it now, it may take 20k or more (on top of the 10k) to make it roadworthy. With that in mind, it may make more sense to buy a Pantera for 25k that needs minor work and can be driven right away.
It is an awesome and very enjoyable car to own. For me, the 'head turning' factor is a very small part of my Pantera experience.
Good Luck!
Michael
