Help me buy this Demon!!!

I have been talking with a guy who has a buddy who has this 71 Demon for sale. He claims that it is all original. No paint or bodywork has ever been done as far as he can tell. His buddy is supposedly the second owner of the vehicle. It is a slant 6 with a 3 speed manual on the column. He said that he hasn't been able to find any rust anywhere on the car. The only known defects are it needs tires (I have a set), the driver's seat is ripped as is the headliner. He says that it is a solid driver, no surprises. Here are some pictures.











His buddy is asking $3000 for the car, but he said he would be willing to entertain offers. So my question is, how much CASH should I take tomorrow in order to drive this car home!!
