Notable features included a three-panel sliding glass roof, and a reconfigurable mid-gate and window that could create a rear cargo compartment separate from the passenger area.^[4] This idea was later used on vehicles like theGMC Envoy XUV andChevrolet Avalanche. Similar to the rear doors of aminivan, the rear doors opened by sliding toward the rear of the vehicle parallel to its sides. There were noB-pillars, and the front passenger seat couldswivel to face the rear seating area.^[4] The interior of the vehicle was surrounded by translucent green lighting, and it included sophisticated electronics such as alaptop computer integrated into the dashboard and anOnStar system.^[5]
