Subaru Legacy
Subaru Legacy — spec data and generation history.

The Legacy was Subaru's full-size saloon and estate — the Outback's sister, less rugged. Six generations from 1989 to 2018 in the UK, all flat-four / flat-six, all symmetrical AWD. BC/BJ Mk1 (1989-1994) was the original; BD/BG Mk2 (1994-1999) brought the Outback variant; BE/BH Mk3 (1998-2003) added the H6 3.0; BL/BP Mk4 (2003-2009) is the sweet spot — sharper looks, GT spec-B with twin-scroll turbo; BM/BR Mk5 (2009-2014) was bigger; BN/BS Mk6 (2014-2018) was the last UK car before discontinuation. JDM tuner cult-favourite Mk2/Mk3/Mk4 GT with twin-turbo flat-four. The Mk4 GT spec-B is the keeper.
