Market Position:
The 2000 Subaru Legacy represented Subaru's mid-size sedan and wagon offering, competing in a segment dominated by the Toyota Camry, Honda Accord, and Ford Taurus. It was known for its standard Symmetrical All-Wheel Drive (AWD) and horizontally opposed 'boxer' engines.
Competitive Analysis:
Key competitors included models known for reliability, comfort, and fuel efficiency. Subaru's differentiator was its standard AWD system, appealing to buyers in regions with inclement weather or those seeking enhanced traction and stability. The boxer engine layout also contributed to a lower center of gravity, improving handling dynamics.

Model Evolution:
The Subaru Legacy, introduced in 1989, replaced the Subaru Leone. The 2000 model year falls within the second generation (BD/BG/BK), which was produced from 1993 to 1999, with a significant facelift for the 1998 model year. Thus, the 2000 model year is technically the last year of the second generation's production run before the third generation (BP/BL) arrived for 2005.
Production Location:
Primary production was at Subaru's main plant in Gunma Prefecture, Japan.
