You should make as many contacts as possible with knowledgeble Pantera people and have them perhaps evaluate the car. It really is bottom-line as to what image you desire the finished product to produce. Will it be an attractive daily driver, or a show car. There can, and will be, many unforseen expenses. I'm into my daily drive over $13,000 so far And Im in a position to get jobber costs on prices and engine building.
I think it would be safe to say that I am about 30,000 away from what I want the car to be, not counting paint.
