Question: "When people purchase the BMW M5, what other options do they tend to buy at the same time?" The data can be mined to show that when people come and purchase a BMW M5, they also tend to purchase the matching luggage. (This is also known as basket analysis). Using this data, the car dealership can move the promotions for the matching luggage to the front of the dealership, or even offer a newspaper ad for free/discounted matching luggage when they buy the M5, in an effort to increase sales.
