A car dealership has asked you to design a database to help them run their business. Here are the operational details:

• They sell new and used vehicles.
• They want to track the vehicle inventory on their lot.
• They may sell a car and reacquire it (trade-in, re-purchase, etc...)
• They want to maintain a record of sales.
• They want to track customers, including potential customers.
• This is enough information to model the database but if you have questions then ask the customer!

Create a conceptual ER model database diagram for the dealership. You can use Lucidchart or another tool.
