Buick Terraza

The Buick Terraza is a minivan from General Motors' Buick brand that was sold from the 2005 through 2007 model years. It filled the position of GM's luxury minivan that was previously occupied by the Oldsmobile Silhouette until the division's demise in 2004. The Terraza was built alongside its Chevrolet, Pontiac, and Saturn sisters; (Uplander, Montana SV6, and Relay) in Doraville, Georgia. Contrary to popular belief, the Terraza was not Buick's first minivan – the GL8 debuted in China in 2000, where it was solely marketed and is still produced and sold today.

The chrome-trimmed Terraza was the most luxurious and costliest of the GM minivans, starting at US$28,110 in 2005. The Buick debuted with one engine, a 3.5 L High Value V6 that generates 200 hp (149 kW) and 220 lb·ft (298 N·m) of torque, going from 0-60 mph in the 9-second range. For 2006, a 3.9 L LZ9 V6, with 240 hp (179 kW) and 240 lb·ft (332 Nm) torque, was added as an option, which delivered faster acceleration and better response. It offered leather seats, and a wood trim on the panels and also offered on the steering wheel and gear shift knob unlike other GM minivans.

For 2007, the 3.5 L V6 was dropped, leaving the 3.9 L as the base engine. Consequently, the optional AWD system was also dropped, since it could not handle the torque of the 3.9 L engine. A flex-fuel version of the 3.9 L V6 also became available for the Terraza's third season. The 2007 Terraza equipped with side airbags scored a "good" in the frontal offset and an "acceptable" in the side impact Insurance Institute for Highway Safety (IIHS) crash tests.
