This seems like such a little addition to the game to have but a link when you click a car / shadow from the Car Collectors screen that takes you to the auctions for that car so you dont have to remember car name > menu > garage >auction house >search > filter through search for the car your after.
When your in your garage and you select a vehicle, “Sell in Auction house” link.
How about a link on the clean lap time accolades to that specific race.
Little QOL updates like this would benefit users so much.
