Terraza's build quality meets or beats the best in the class, and it has the minivan essentials covered. It comes standard with a V6 engine, and it's available with all-wheel drive. With the optional towing package, it can pull 3,500 pounds.
For 2006, the Terraza offers side-impact airbags for rear passengers, and Buick has increased the standard warranty to a premium-grade four years or 50,000 miles. Yet the biggest news for 2006 is an optional 3.9-liter V6 with variable valve timing and a 22 percent increase in horsepower. Choose this engine and Terraza morphs from one of the least powerful minivans available into one of the most powerful.
That's good, because if Terraza falls short of the best in class, it's most obvious in the driving. The standard 3.5-liter V6 is adequate, no more. And while Terraza is quiet and comfortable in the Buick tradition, it feels less responsive than the minivans from Chrysler, Honda, and Toyota. That more powerful 3.9-liter V6 should help.
For now, Terraza's real strength lies in other important minivan virtues, and to considerable extent in its value. Comparably equipped, it retails for less than the Chrysler Town & Country or a loaded Toyota Sienna, and that's before the incentives GM frequently offers.
Like its contemporaries from Chevrolet, Pontiac and Saturn, Terraza stands on more solid competitive ground than previous GM minivans. It shares its chassis and mechanicals with the Chevy Uplander, Pontiac Montana and Saturn Relay, and the differences are defined by minor styling changes and varying equipment levels. While each brand may indeed appeal to different buyers, smart consumers will shop them all. Price differences among the GM minivans amount to a few dollars when they are comparably equipped, and all are available with the most popular features. The choice may come down to satisfaction with a particular dealership.
Like its GM counterparts, Terraza's long-nose, truck-style exterior design is intended to create the image an SUV more than a minivan. We say no one will mistake the Terraza for anything but what it is: a minivan with the flexibility, features and family-friendly conveniences minivan buyers expect.
