Impreza 22B STI
424 units built (400 Japan-market numbered cars + 24 export) — the most consistently cited "rarest Subaru"
424 total is the figure with the broadest support across sources, but the export-market breakdown of those 24 cars is disputed and preserved rather than resolved: one prior research pass reports 16 UK + 5 Australia + 3 prototypes, while a source used this pass reports 16 UK + 8 "rest of world" — both total 24 but partition differently, and neither cites a primary Subaru production ledger. A minority of sources cite 425 or a plain 400 (ignoring export cars); recorded as weaker variants, not adopted. Two headline auction results, both preserved with their own disputes: (1) a JDM-spec 1998 22B personally imported under the US "Show or Display" exemption sold on Bring a Trailer for $312,555 on 20 April 2021 after 76 bids — a separate, unconfirmed Hagerty-reported figure of $317,555 for what may be the same or a different April 2021 sale could not be verified this pass (source returned an HTTP 403); (2) a 22B marked "000/400" — an ultra-rare pre-production prototype, not a numbered production unit — owned by Colin McRae since new, sold at Iconic Auctioneers, Silverstone, on 30 August 2023 for £480,500, reported as one of three total prototypes (the other two going to co-driver Nicky Grist and Prodrive engineer David Lapworth). This conflicts with a separate Bonhams lot description (chassis GC8-061819, also gifted new to Lapworth) stating five total prototypes were built — three vs. five is unresolved. A widely-repeated "$827,000" figure appears on inspection to be the Iconic/Silverstone result quoted in Canadian dollars rather than a separate Bonhams sale, but the two auction-house sources could not be fully disentangled this pass and are recorded separately rather than merged into one narrative.
