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.<ref name=conceptcarz-TC/> This idea was later used on vehicles like the GMC Envoy XUV and Chevrolet Avalanche. Similar to the rear doors of a minivan, the rear doors opened by sliding toward the rear of the vehicle parallel to its sides. There were no B-pillars, and the front passenger seat could swivel to face the rear seating area.<ref name=conceptcarz-TC/> The interior of the vehicle was surrounded by translucent green lighting, and it included sophisticated electronics such as a laptop computer integrated into the dashboard and an OnStar system.<ref name=MT-TC/> {{clear|right}}
