Satellite radio is newly available for Chevrolet's version of GM's mainstream minivans. Venture's basic design is shared with the Oldsmobile Silhouette and Pontiac Montana. The regular-length Venture comes only in a Plus model for '04. Extended-length versions have an 8-inch-longer wheelbase and come in Plus, LS, and LT models. All Ventures have a V6 and automatic transmission. Traction control is optional on LS, standard on LT. LT also offers GM's Versatrak all-wheel drive; it includes independent rear suspension and 4-wheel disc brakes. A power right-side door is available for LS models. Dual power doors are available for LT models. Seven-passenger seating is standard, 8-passenger seating optional on LS and LT. The standard 2nd-row bench has an integrated child-safety seat. Standard on LT and optional on LS are 2nd-row buckets without an integrated child-safety seat. Front side airbags and ABS are standard on all but Plus models, where they're optional. Other options include rear-obstacle warning, load-leveling rear suspension, and a stowable 3rd-row seat. Exclusive to LT is standard rear DVD entertainment. For '04, satellite radio is optional for LS and LT, and the uplevel CD player also plays MP3-encoded CDs.
