To build or to buy? Back in the good old days, if you wanted a hotrod you had to build it yourself. That meant that you had to know a thing or two about all the different forms of fabrication - from welding, machining, bodywork and painting, to engine an transmission rebuilds. Unlike today, where you can have a car built by a professional team or find one to buy at a collector car auction. Any way you slice it, it isn't cheap; though it's not uncommon for street rods to sell at a steep discount compared to their original build costs.
