AI market analysis

For buyers

With an eBay median asking price of $137,308, this 'Concept' reference is currently trading very close to its original $135,000 MSRP. Given its low liquidity and avant-garde appeal, focus negotiations towards the lower end of the $140,000-$160,000 grey market range, aiming for a price point closer to $135,000-$138,000 for a solid deal.

For sellers

Given its rarity (8) and low liquidity, position this 'Concept' as a niche collector's piece, highlighting its avant-garde design and GMT Tourbillon movement. To attract serious buyers in the $140,000-$160,000 grey market range, list competitively between $142,000 and $148,000, as the current eBay median sits at $137,308.
