Welcome, Byron.
I will add my voice to the chorus who advise buying a used one. They're a little cheaper and often (not always) are somewhat pre-sorted.
"Sorted" you say?
Yes! In the days of yore, the sporting gentlemen was obliged to correct all the minor deficiencies of his vehicle after delivery. These tended to run the gamut from faulty, or imprecisely-aimed headlamps to ever-so-minor oil drips from various mechanical systems, to a persistent off-idle stumble. Shifters may require adjustment; float arms bending, suspensions alignment. And all this is prior to the Necessary Upgrades, to include cocoa mats, special badging and custom steering wheels, etc.
Most new owners get it exactly backwards, putting all the nifty accessories on before the first shakedown drive. Many never fully sort their car.
They all need a little sorting, which is why Gordon suggested the geographical considerations listed above. Both Beck and Vintage tend to help this process with a gentle professionalism seldom seen in today's market. They tend to extend a helping hand even to second-hand customers. Very few such customers will say a disparaging word about either company, and those who will tend to reveal themselves as the unrealistic, petty bummers they tend to be.
All of which is to say: be realistic. These cars are not real 1957 Porsches, but they are built primarily from the same suite of technologies extant during the latter Eisenhower Period. These parts are what imparts their charm.
