o·rig·i·nal: [uh-rij-uh-nl] / adjective belonging to the origin or beginning of something, or to a thing at its beginning. ie: The book still has its original binding. " A car is an original when it's original " Tom S. in Tn. 2011 That would include carburetors, transmission. scattershield, or air in the tires. I'll return to the Tucker analogy because their numbers closley represent T'bolts where Mustangs were mass produced many years in the thousands. How original would a Tucker be without an original carburetor or transmission? Bet the Tucker registry as well as show purists would cite as well as make a public example of it. Practically every Tucker produced is known with it's owner and appropriately registered, where, with historically the fate of what racing did to DST Fairlanes, those cars are no where near having the survival rate, making them from all appearances, a far more valuable investment pound for pound than perhaps a Tucker, even in a butchered and partial complete condition, so long as those pieces are factual and actual DST Fairlane parts, andnot restoration, reproduction, or aftermarket made to simply resemble one of the 100 DST original. I can't see why that would not even include parts such as the windows mentioned. (which by the way are the original thick plexi 1/4 windows are out of #87, have no trademarkings, only original Autolite decals still in place from #87's original owner, visible in photo's of #87 taken in 1964) Those windows, not at all unlike original windows from a Tucker, or an original carburetor from a DST Fairlane should command quite a present day value, even as just separate parts. It's all in the documented proof. In the case of DST Fairlanes, unlike a Tucker I suppose it's safe to assume there are no living examples of an "as delivered state", with only parts manuals and personal recollection the only yardstick to judge an example by. With that being the case, the surviving examples as close to as delivered would be the most valuable and considered at the top of the list with deviations from original "as delivered" state going down the list to include altered wheelbase etc at the lower end, and with those cars retaining higher value in their present historic "as is" state rather than modified even yet further to return and make them resemble an original, or "as delivered" condition. If 45 surviving examples are known to exist, only the original DST parts of those examples are of any exceptional value, and of anything different than any other Fairlane or aftermarket car or part, or even Ford for that matter........ despite what car clubs or marketeer brokers say. It's all in originality, and not just a teardrop hood or a 427 engine, or even a reproducible VIN#. (and I'm still shocked at some of the sincere examples I've seen displayed in all sincerity and honesty on the unwitting owners part) How many DST Farilanes will be present at Dearborn in 2014? There potentially could be thousands or even original DST parts on hundreds, but how many of the actual DST bodied cars could presently be able to be transported there some 50 years later, let alone one of the original carburetors? Wish I could have envisioned an original DST Failane was far too valuable to risk damage by racing. And I can't see why that wouldn't apply even exponentially today. Who would dare risk damage to a Tucker investment? Who would take risk with an original DST Fairlane? Anyone in he registry needs to put limits on how the cars in that registry are expected to retain investment value, and only the registry can do that. Could we be seeing a trend in that with current sales and pricing? Good luck guys! Tom S. in Tn.
