Hey all so basically I have a C# application that allows a user to enter their query about cars in stock (Fields are Car Manufacturer, Model, Age, Litre Size).

The query's contents can vary on what fields the user is looking for (e.g. a person may look for all Ford cars or another query may be all Ford cars that are 6 years old).

After the query is entered the program SHOULD return the data requested to a dataGridView...
