What are examples of materialism shown in this novel?i need as many examples as possible please

In addition to the above answer, there are also the following examples of materialism:

Cars: Tom and Gatsby sport the most expensive autos on the market.  Wilson wants to buy Tom's car, but Tom won't sell it to him.  As a result, Tom holds his superior car status over Wilson.

Women: They are status symbols, too, just like cars.  Men like Tom collect mistresses like model-Ts.  In the end, when they're an old model or dead, he gets a new one.  Remember, Myrtle is killed by a car.

Liquor: This novel takes place during Prohibition, a time when alcohol was banned from public consumption, but that doesn't stop it from flowing to excess during the parties.  Champagne and Mint Juleps are in nearly every chapter.
