Human: I'm trying to decide which type of car to buy. I'd like to know what the difference between a sedan, coupe, Assistant: 
A sedan is typically a four-door car with a more spacious interior than a coupe. It has more legroom and headroom for passengers, as well as more storage space inside. The engine is usually placed further back in the chassis so that it doesn't intrude into the passenger compartment. Coupes are two-door cars that have a more aerodynamic design and often feature a lower roofline. This allows for more wind resistance at high speeds, but also provides more visibility from the driver's seat.
