The way I see it. Don't think I have heard of a better analogy.
1960's (Original) Rolex Submariner - (Continuation) New Rolex Submariner
Both are genuine Rolex Submariners. There are plenty of knock offs for much less but bring them into a Rolex dealer and they quickly tell you its not a Rolex. Same can be done with a inspection of a Shelby Cobra by a qualified Shelby expert and by referencing its CSX vin # via the Registry.
I apply the same logic to the (Original) Shelby Cobras and the Aluminum (Continuations). Both similar in nature with same company building them. Im sure there aren't many employees left building new Rolexes that built the first original Submariners, but the company still makes Genuine name brand product today. The early (Original) Rolex Submariners are very coveted by the collectors who own the handful of them out there. Some own both. "In house movement" may apply some how as well to this analogy...LOL
Sorry to add another line in this never ending topic. After seeing it at the top of the page the last few times I opened the site, I had to click on it, and for fun add my 2 Cents.
In all reality we will all be dead or close to it in 40 years who knows what the cars may or may not be worth then. Im pretty sure none of us will be right if we guessed today. What ever we own, we own because we liked it enough to step up and buy it, who cares what anyone else thinks. Drive the hell out of it and have fun! Cheers boys!
