The Buick Terraza was the first minivan by Buick to be marketed in the United States. Upon the demise of Oldsmobile, General Motors shifted the production of a luxury minivan over to the shoulders of Buick. The Terraza was designed to fill the slot left by the out going Oldsmobile Silhouette. While the Terraza was the first minivan for Buick in the United States, it has produced the GL8 since the year 2000 for the use solely in China.
The Terraza was on the market for just two a few years, 2005 through 2007. It was produced exclusively in Doraville, Georgia along with the Chevrolet Uplander, the Pontiac Montana SV6 and the Saturn Relay.
The Buick Terraza was debuted as the most luxurious and well appointed of all the General Motors minivans and had a price tag to prove it. This vehicle had a starting price of $28,110 when it was introduced in 2005.
Though the most luxurious of all the minivans, the vehicle was only offered with one engine that first year, although two other engines would be included at some point before the model was discontinued. These three Buick Terraza engines included the 3.5 L LX9 V6 engine, the 3.9 L LZ9 V6 engine and the 3.9 L LGD V6 engine. All three engines were offered with the same tranmission, a four speed automatic. The 3.9 Liter engine was added in 2006 and the 3.5 Liter engine was dropped in 2007. Though the Terraza came with all wheel drive originally, this feature was discontinued in 2007 when the 3.5 Liter engine was dropped as the all wheel drive system could not adequately handle the torque of the larger engine.
For the last year of the Terraza, a flex fuel engine was also made available, as were side airbags. Though Buick continued to make changes to the Buick Terraza, the public was unimpressed and sales were never spectacular. The model was dropped for 2008 and the minivan was replaced by the Buick Enclave.
