Darth Vader finds your lack of floor mats disturbing, so you should probably get the Darth Vader Car & Truck Front Floor Mat 2-Pack just to keep him happy. He tends to force choke people when he gets angry.
These are probably the same mats they have in TIE Fighters and AT-ATs. No matter the vehicle, it’s just gonna end up collecting gravel and crumbs. These universal car/truck floor mats feature an outline of Darth Vader’s helmet, with the background filled with Sith/Imperial symbols.
