It seems plenty of reproduction steel parts are already available. Considering that original Speedsters are now in excess of $250,000 a correct steel reproduction seems a rational idea. Obviously getting a steel reproduction registered could be a problem but it is not insoluble. The 1959 356A Speedster GT/GS used several aluminum panels and this could incite your interest? There IS a market for a real Speedster replica. One needs only to browse this site to see the lengths owners go to trying to replicate the originals! Having owned actual Speedsters and now a Replica for me it's about how a car feels. Replicas not only look like what they were inspired by, they DRIVE often better than the cars produced from 1954 to 1959! Any reproduction should closely represent the car that was and recreate the FEEL of the original!Remember the car produced by Porsche in 1954 was a stripped down version of their Cabrolet and was marketed as the LOW Cost pure Sports Car. The Speedster became an Icon reaching unreasonable value, and unobtainable for those who cherish what it DID as a Sports Car . One should keep in mind that we who drive replicas today do so NOT ONLY because they are fashonable, or will increase in value, but because they are reasonable to buy, and FUN to drive, exactly what the original buyers did!
