Doors
A car door is the hinged (or sometimes sliding) entry point into a vehicle’s cabin.
On trucks and SUVs, the door design is often reinforced to handle off-road use, while luxury cars may add soft-close systems and frameless windows.

Conventional Doors – Standard hinged at the front, most common.
