Montana is built from the same design as the Chevrolet Venture and Oldsmobile Silhouette. It offers regular- and extended-length bodies, both with dual sliding side doors. Seating ranges from six to eight passengers, with two front buckets and two or three 2nd-row buckets. Third-row is a 3-place folding bench. All Montanas have a 3.4-liter V6, automatic transmission, ABS, front side airbags, puncture-sealing tires, and the OnStar assistance system. Traction control is standard on regular-length 7-passenger models, optional on extendeds. Other options include load-leveling suspension and a tauter sport suspension. Montana's performance and accommodations mirror those of similarly equipped Chevrolet Ventures. There is a tv and vcr entertainment system.
