Have in been having a hard time making a decision regarding our Signature X and its potential future value. To contrast, I am very happy with the decision I made to trade in my 2013 Model S for my 2018 Model 3. It was spectacular upgrade which speaks volumes to the pace of innovation that Tesla is moving at, although the 2013 did have some notable issues for its time, most of all its lack of AWD. The Model 3 is first in its price class by any measurement, IMO. When we first got our 2016 Signature Red Ludicrous it was the best car on the road, with an AP that was unmatched in any production car. It is still awesome. BUT, the AP will never get better and cannot become FSD on any level. The range is nowhere near what we can purchase now. And there have been numerous other improvements that I cannot keep track of. From this perspective it is easy to see why we would trade in or upgrade. Except...fast forward ten years to where Tesla is (at least IMO). in 2030, Tesla makes the best BEVs and is a dominant and global large OEM. Its cars are lauded the world over. The company is universally acknowledged as a disruptor par excellence for having brought the ICE era to its knees and demise almost single handedly and led the way to the current BEV and renewable present. And the very first models...begin to appreciate as the classics that they are. My Model S was one of the first 10,000. But it was not a Sig and I feel I made the right choice. The Sig X OTOH, is not a founder's edition but still classifies as the very first edition of the X. It is loaded and in its original condition (the car was wrapped on arrival and has low mileage). Will this car be in demand as a classic and as such worth keeping? I do have the option of mothballing it when I pick up my Y. Have I lost track of reality and need to come to terms with the fact that these cars age fast, and no one will ever want yesterday's technology? Haven't I figured out that this will only apply to certain early Roadsters and Model S's? All comments, opinions and votes are appreciated!
