Yes, you can put a back seat in certain vehicles according to your needs, particularly those with removable or highly flexible seating options. For instance, the Honda Odyssey minivan features the "Magic Slide" center row, where the middle seat can be removed and the outboard seats can slide side to side, offering numerous seating configurations and enhanced access to the third row. The 2023 Honda Pilot also allows you to remove the middle seat in the center row, which can be stowed under the rear cargo floor, providing the flexibility to choose between seating for seven or eight passengers. Additionally, some SUVs like the Chevrolet Suburban and GMC Tahoe have third-row seats that can be easily removed without tools, using handles and roller wheels to facilitate the process. This is particularly useful for those who need maximum cargo space and do not require the rear seats. Vehicles such as the VW ID. Buzz EV and certain Ford models also offer removable or highly adjustable seating, allowing for a range of configurations to suit different needs.
