Subaru Impreza 22B-STi (NA)

The Subaru Impreza 22B-STi remains one of the rarest production cars ever made, with only five units built for the Japanese market in 1998. This extreme scarcity alone places it in the "Holy Grail" collectibility tier, though UK market data is essentially nonexistent—no sales have been tracked in the past 12 months, and there are currently no active listings.

The absence of transaction data reflects the fundamental challenge with this car: it is almost never offered for sale, and when it does appear, it typically transacts outside conventional auction channels. Any UK-based 22B would likely command seven-figure sums based on comparable sales in Japan and the United States, but without documented UK transactions, specific valuation trends cannot be established.

Liquidity is effectively zero for practical purposes. Potential buyers at this level are typically institutional collectors or ultra-high-net-worth individuals who operate through private negotiation rather than open market purchase. The lack of comparable recent sales means traditional price discovery mechanisms do not apply.

The car's classification as an appreciating classic reflects its status as a homologation special built to celebrate Subaru's World Rally Championship success. Condition, service history, and originality would be paramount to any valuation, but mileage norms cannot be determined from available transaction records.

Without tracked sales activity or price signals, forward projections for the next three to five years cannot be meaningfully calculated. The 22B's trajectory will remain driven by wider collector sentiment toward Japanese performance icons and the scarcity premium attached to sub-ten-unit production runs, rather than by domestic UK market dynamics.
