Exotic Cars Inc. (ECI) is a company specializing in sales and maintenance of the exotic (hence the name) cars.

The cars that ECI sells come from multiple sources: some are shipped directly from the factories, other purchased from the private collectors, and yet some other cars are traded-in by the customers of ECI.

ECI also provides a regular maintenance service of the exotic cars, such as engine tune-up, tire rotation, oil change, etc. You do not have to buy a car from ECI to use its maintenance service; consequently, some owners of the exotic cars purchased elsewhere also use ECI maintenance service.

ECI appreciates continuing business of its patrons; consequently, the company wants to maintain as much information about each valuable customer as it possibly can.

As a result, ECI diligently records how much money each customer spends on buying cars (more than a half have purchased two cars and about third bought three or more), on maintenance service (how much customer spends overall, and per car), and whether or not a customer ever traded a car in.
