The Buyer's Read
Start by deciding which Forester fits your situation. A clean SG XT with documented service history is the practical pick for most buyers — it carries the EJ255 turbo, parts are sourced domestically without import friction, and Bring a Trailer sold results give a reliable baseline on where clean examples are currently landing. Skip anything priced under $5,000 unless you're buying it for parts; the head gasket job alone on a neglected 2.5L EJ25 will cost more than the car did.
For import buyers, the SF5 STi became eligible under the 25-year rule in 2023. The EJ20K turbo, the 5-speed manual, Brembo brakes, and the hardware shared with the Impreza WRX STi of the same era make it a legitimate performance car in a wagon shell. The catch is supply: most clean SF5 STi cars remain in Japan, and the landed cost typically exceeds what a US-market SG XT commands.
The 2029 opening of the SG Forester STi is the longer-horizon play. EJ255 turbo, 6-speed manual with DCCD, Brembo brakes, an aluminum hood with a functional scoop, and WRX STi bucket seats — it is the rarest factory Forester variant ever built, and prices in Japan reflect that. On any turbo Forester regardless of generation, ask for paperwork covering the tune and the fuel used. A modified EJ20T or EJ255 run on a bad map or incorrect octane can carry ringland or knock damage that does not show up on a cold-start inspection or a short test drive.
