Citroën GS Birotor

The Citroën GS Birotor sits at a median valuation of $23,643 in the US market, though this figure rests on an extremely limited transaction base of just one recorded sale over the past twelve months, making any trend assessment impossible at this time.

With only 847 units produced worldwide, the GS Birotor occupies the rarest tier of classic French cars and commands a "Holy Grail" collectibility score of 9. Its significance lies almost entirely in its historical peculiarity—it was one of the only production cars ever powered by a rotary engine fitted by Citroën—rather than widespread enthusiasm among collectors today.

The illiquid market for this model reflects a fundamental disconnect: despite its technical rarity and high collectibility rating, desirability remains low among active buyers. No current listings are tracked in the US market, and the single sale that anchored the $23,643 median likely represents an opportunistic transaction rather than evidence of sustained collector demand.

The absence of mileage data and the minimal transaction history prevent any reliable assessment of typical condition norms or price momentum over the coming years. Prospective buyers or sellers should expect extended holding periods and regional search requirements to locate interested parties, as this remains a specialist's car rather than one with accessible market depth.
