Venture's least-expensive versions make antilock brakes and front side airbags optional instead of standard for 2003. Regular-length Ventures come in Value, Base, and LS models. Extended-length versions have an 8-inch-longer wheelbase and come in LS, LT, and top-line Warner Bros Edition models. All have a V6, automatic transmission, and dual sliding side doors. A power right-side door is available for LS models. LS, LT, and Warner models offer optional dual power doors. Most Ventures have 7-passenger seating. An 8-seat setup is standard on Warner, optional on LS models.

Most come with a 2nd-row bench that includes an integrated child safety seat. LTs have 2nd-row captain chairs without an integrated child safety seat. Warner Bros models have three 2nd-row buckets with a child safety seat.

Front side airbags and ABS are now packaged as a $950 option on Value and Base models. They remain standard on other Ventures. Most Ventures have front-wheel drive and available traction control. Extendeds offer GM's Versatrak AWD; it includes independent rear suspension and 4-wheel disc brakes. Other options include rear-obstacle warning and a stowable 3rd-row seat. Exclusive to LT Entertainer and Warner Bros models is standard rear DVD entertainment. Venture's basic design is shared with the Oldsmobile Silhouette and Pontiac Montana.
