Expert Insight

• Since the 2003 Pontiac Montana 3400's engine specifications match those of the Venture and Silhouette, "there is no difference in driving experience" among the three models, according to the website Cars. Pontiac does offer the option of all-wheel drive, although the difference is not noticeable, and provides the driver with only "a feeling of added confidence," Cars adds.
