The compartment is most often located at the rear of the vehicle, as storage areas are normally at the end of the vehicle opposite to which the engine is located. Some mid-engined cars (such as the Porsche 918 Spyder) and rear-engined cars (such as the Volkswagen Beetle and the Porsche 911) have the trunk situated in front of the passenger compartment. Vehicles such as the Volkswagen Type 3 have storage compartments both in the front and in the rear, with the rear compartment above the low-profile boxer engine. The mid-engined Fiat X1/9 also has two storage compartments, although the rear one is very small, but practically cuboid in shape. Sometimes during the design life of the vehicle the the lid may be restyled to increase the size or improve the practicality and usefulness of the trunk
