Buick received its first minivan for 2005. Terraza shared its basic design with the 2005 Chevrolet Uplander, Pontiac Montana SV6, and Saturn Relay. All basically added an SUV-style nose to the 1997-2004 GM minivan design to create what GM dubbed the "crossover sport van." Terraza was the costliest, most luxurious version, and was the only one to come standard with load-leveling suspension. Terraza offered CX and uplevel CXL models. There was one body length and seats for seven via folding/removable 2nd-row bucket seats and a 50/50 fold-flat 3rd-row bench. A power sliding passenger-side door was standard on CX; CXL added a power driver-side door, which was optional on CX. Terraza used a 200-hp V6, 4-speed automatic transmission, and either front- or all-wheel drive. Front-drive models had GM's Stabilitrak traction/antiskid control. All models came with 4-wheel antilock brakes, 17-inch wheels, and OnStar assistance. Front side airbags providing head and torso protection were optional on CX and standard on CXL, but curtain side airbags weren't offered. Also standard were a CD/MP3 player, DVD entertainment, and a roof-rail system with available snap-on storage modules. Rear air conditioning and a rear cargo organizer were optional on CX, standard on CXL. CXL also added leather seating surfaces and rear obstacle detection. Among the options for both models were satellite radio and a remote starting system that operated from the keyfob.
