Depending on the design of the aftermarket car mats, they should easily fit your car in pretty much the same way as OEM floor mats. This is especially true for vehicle-specific or model-specific auto floor mats. These types of car floor mats are specifically designed to fit the floor space of your specific type of vehicle. Now there are also universal types of auto floor mats that can be easily cut or timed to make a perfect fit. The degree of fitness is dependent on how well you are able to accurately measure the dimensions of your car’s floor area.
