Navigating GTA Online's vast array of purchasable items can be daunting.
Over the course of over three years, GTA Online has, through a constant stream of free DLC, built up an absolutely massive library of items, vehicles, weapons and properties available for purchase in-game. For new or returning players, the sheer amount of stuff to choose from might feel overwhelming.
How are you going sort through it all and find the best things to buy in GTA Online?

As the number of vehicles, weapons, properties and additional items (customization, upgrades, yachts, offices, warehouses, businesses, clubhouses) continuously increases while the price of goods in GTA Online are pretty high (we cover the reason for that here), it is especially important to make sure you buy something you won't regret later.
Those items that can be sold only return a small percentage of the purchase price, while there are many — especially among the particularly expensive purchases — that cannot be sold back at all. As such, unless they want to lose out on a lot of cash, the discerning player will do some research as to what should be bought while keeping in mind their GTA Online character's bank balance.
