Marque analyst note
The Subaru Forester STi SG9 is trading at a median of £12,000 in the UK market, though the extremely thin sample of just two transactions over the past twelve months makes any trend assessment unreliable. With no active listings currently recorded, this model sits in a distinctly illiquid corner of the market where price discovery happens infrequently and buyer-seller matching is challenging.
Classification as an appreciating classic reflects the model's growing status among enthusiasts, supported by a collectibility score of 6 out of 10. The SG9-generation STi variant occupies a niche segment—performance-focused Foresters have never commanded mainstream demand, but their rarity and technical interest have begun to register with a dedicated subset of collectors focused on Japanese performance cars from the early 2000s.
The lack of available mileage data on transacted examples leaves the condition-to-value relationship unclear for this model. Future buyers will likely need to assess each car individually without a strong dataset to benchmark typical usage patterns or maintenance histories across the market.
With only two sales tracked to date, the dataset is too sparse to support meaningful projections or directional calls over the next three to five years. Dealers and private sellers should expect longer lead times to find qualified buyers and should price competitively to stand out in an essentially dormant secondary market.
