# Upgrade Bay

Selects an owned vehicle (`selectedId: "muscle"`) with `conf_comp.showUpgrades: true`, which renders the Upgrade button in the detail panel - the button only appears for cards whose `owned` flag is true. Clicking it calls `upgrade(vehicleId)` and fires the `xwui-garage-upgrade` event, while the surrounding stat bars (shown because `showStats` defaults on) let the player gauge what the upgrade should improve.
