I think you know the answer to that question. I think the question you need to ask is all that work worth the price.
While Mark is right and you always save money by buyiing the best example you can afford but I must be weird becuase for me its not always about the destination. Sure you could buy a completed car and have someone else's idea of the perfect Pantera that you just drive and enjoy. I did this with a '96 Bronco. All lifted, painted, really nice stereo, 38" BFG Mud T/A's etc etc. Very cool truck that got a lot of looks but it never really felt like it was mine. People would ask me "How you do this?" "How'd you do that?" and I would have to say the previous owner did it. Sure I could have lied but for what?
My son and I are working on building a "68 Mustang coupe. I'm into it for way more than its worth (and its not yet done) but the fun I alone have had not to mention my son AND daughter is priceless. I would never have that if I just wrote the check.
So to answer your question: if you want to drive and enjoy now buy a complete car. If you want to take a journey with the Pantera offer them $10K......
