At the beginning of the 2000s, few car manufacturers offered upscale MPVs, so when Buick launched the 2005 Terraza, it surprised the market. GM sought to maximize returns on the platform it developed for the Chevrolet Uplander and Pontiac Montana, leading to the creation of the more luxurious 2005 Buick Terraza. As the brand’s first minivan, it was manufactured in Doraville, Georgia, and marketed to large families with higher incomes who wanted a vehicle suitable for both school drop-offs and business meetings. Despite its premium features and Buick badge, the Terraza failed to gain lasting traction, and GM discontinued it after just three years without offering a direct successor.
The exterior design of the 2005 Terraza aligned with Buick’s upscale aspirations. It featured an upright front grille with chromed vertical slats and a centered brand badge. The slightly recessed headlights offered extra protection against minor impacts. Beneath the headlights, Buick added rectangular daytime running lamps integrated into a plastic bumper, and the lower apron carried a secondary air intake accented with three vertical slats.
With its tall silhouette, the 2005 Terraza aimed for an executive yet family-friendly appearance. It came in two trims - CX and CXL. The CX had standard 17-inch steel wheels with optional aluminum upgrades, while the CXL featured premium chrome-tech aluminum wheels. Like many minivans of its time, the Terraza used sliding rear doors - manual on the passenger side for the CX trim and dual power sliding doors on the CXL. At the rear, large, corner-mounted taillights framed a wide-opening tailgate for easy access to the cargo area.
Inside, Buick invested heavily in refinement to set the Terraza apart from its platform mates. Two front captain chairs offered optional leather upholstery, and the dashboard featured wood grain accents and a classic four-gauge cluster. On the center stack, a CD/MP3 player came standard, with available upgrades including a six-disc changer or a touchscreen navigation system. The middle row skipped the traditional bench seat in favor of two captain chairs, separated by a center console with cup holders and a storage bin. The third-row bench seat was split-folding and sized more appropriately for children.
Powering the Terraza was a 3.5-liter V6 engine paired with a four-speed automatic transmission. Buyers could choose between front-wheel drive or an optional all-wheel-drive system. Suspension consisted of independent McPherson struts in the front and a multi-link setup in the rear, enhancing ride comfort and handling.
