As beauty is in the eye of the beholder, so is the value of a Street rod. Valueing a vehicle of this nature is very difficult as they are usually assembled using lots of bits n pieces from various donors with a basic resemblance to there former self. I presume you have one in mind. That being said I would say there would be some folks on this forum who may be able to give yoy a ball park figure on what you should be looking at but I doubt you would find a "spreadsheet" with pricings etc.
I would suggest a detailed description and some good photos may help us give you an idea. Of course me being in Aussie makes it even more difficult to value your Street rod as our dollar and economic climate are quite different. PS Welcome to the forum...
