A redesign that focuses on improved safety and extra interior space are the major changes to the 2000 Subaru Legacy. A new GT and GT Limited trim are also added this year. The full-AWD 2000 Legacy is offered in both sedan and wagon versions, all with a 2.5-liter boxer H4 engine that now gets 165-hp with a single-cam engine replacing the dual-cam. A 5-speed manual or 4-speed automatic is available.

Sedans come in L, GT, and GT Limited, all with standard ABS brakes, full power features, and dual front airbags. The GT Limited also has side impact bags. Wagons come in base Brighton, L, and GT. The Brighton has power windows, but full power features are only found on L and GT. All GT models come with a dual-pane sunroof, limited slip differential, sport suspension, and power seats. The GT Limited adds a CD player and leather seats. Rear seats split-fold only in the wagon, not the sedan, to expand on cargo space. The 2000 Legacy has been redesigned with a stiffer body frame and safety features to improve crash ratings. Other additions include front and rear cupholders, daytime running lights, and a larger instrument panel.

The AWD is the biggest selling point for the 2000 Legacy, which led the Subaru lineup in offering the system. Drivers in cold climates say its reliable and powerful. Other favorite features include tight handling, the sporty feel of the GT, and the good gas mileage (around 22/27 mpg). Downsides are cramped legroom overall, the need for lumbar support, and a desire for more horsepower. There are reports of a leaky sunroof and transmission problems in the 2000 Subaru Legacy.
