@bonnie Yes, you make valid points as of today's market. Above I've made the case for the future and urged SIG owners (and I would include Roaster owners too) not to give their cars away. Again:
Factors that go into collectable valuation:
RARITY: YES In my case Elon stopped signing Sigs almost immediately after his staff talked him into it. Only a handful were signed for George B's make me smile campaign including Sig 791. This is even less than the number of Founders Model S's. I met George and Elon at various early Tesla events....they really did appreciate those of us who were early adaptors. Elon is
very gracious autographing almost anything people give him. However, his signature for the historic roll out of the SIG Model S series (ie a "real SIG") has more value to a collector than an
after the fact signature. The car's story counts a lot. I can prove mine was one "a few" signed for delivery.
BODY STYLE AND FLARE: Hell YES!
PEDIGREE: Interesting story - history of ownership
YES!
CONDITION: Less miles may be better but no so much according to Jay Leno. 18,888 is a very good number in Asian culture! Maybe I'll still own it @ 88,888 miles if I can't get a "make me sell" premium!
LIMITED EDITION & CULT FOLLOWING: YES!
Buyers will never pay a collectable premium if we don't ask for one. Your argument is self-fulfilling; mine is theoretical until a buyer steps up and pays over market for my car. Time will tell!
