I always love those ads that say it hasn't been butchered, but has a tacho in the corner and an aftermarket steering wheel. Perhaps butchered is not the right word - it's the sellers comment after all, but they seem so intent on extolling the virtues of it's originality, it doesn't quite go together.
I think you need to determine what it is that you want. In one comment, you are asking about the price for one fairly stock, and the next sentence, you are talking about modifying. For a reasonably stock one, it is a reasonable price, although I would prefer the one that was offered here recently - should be in the Cars for Sale section, and was around $5,000.
If you want one to modify, I suspect you will find one that is a little cheaper - perhaps an incomplete project.
