Selling cars in Forza Horizon is an easy way to turn extra vehicles into Credits you can use to buy anything else in the game you'd rather have. That includes cars you actually want, although the exchange rate isn't the most favorable. Here's how to sell any unwanted vehicles using the in-game Auction House.
How to Sell Cars in Forza Horizon 5
To sell a car in Forza Horizon 5, you'll need to press the menu button and switch to the Cars tab. Select "Buy New and Used Cars," which will then take you to the Horizon Festival site, and offer you a chance to fast travel there. When you arrive, you'll be able to access the Auction House, where players can buy and sell their used cars to one another.
To sell your own car, select the "Start Auction" option. Select the car you want to sell, then choose the "Auction Car" option. From there you'll be able to choose the starting price, auction length and buyout price. With that all set, sit back and wait for the auction to end.
