Alfa Romeo SZ

The Alfa Romeo SZ occupies an unusual position in the collector market: it carries a "Holy Grail" collectibility score despite almost no transactional data to support current pricing. The US$62,260 median reflects an extremely thin market with zero recorded sales over the past 12 months and no active listings, making that figure more theoretical than empirical.

Production of the SZ was limited to just 1,036 units globally, a scarcity that underpins its classic-car classification and high collectibility rating. However, the model's low desirability score and illiquid market standing suggest that rarity alone has not translated into consistent buyer demand or price discovery in the US.

Without recent sales volume to track, any valuation trend remains opaque. The absence of both 12-month transaction history and active inventory means buyers and sellers are operating with minimal reference points for negotiation, a condition typical of deeply specialized European sports cars with limited US representation.

The mismatch between the SZ's theoretical collectibility tier and its practical market thinness warrants caution. Prospective purchasers should recognize that achieving the quoted median price at sale time is not guaranteed, given the absence of comparable recent transactions to validate current asking levels.
