To 'import' or buy a vehicle, the player simply needs to walk up to the board in Easter Basin and select which vehicle they would like to import.
The player will then receive money depending on the type and condition of the vehicle. Once the vehicle is in contact of the marker (and released from the crane magnet, if lifted using the crane), a message will show up that the player has successfully exported that vehicle.
To 'export' or sell a vehicle, the player must obtain a 'wanted' vehicle (as shown when the player is told via an on-screen message: 'You can export this vehicle over at Easter Basin Docks.') and take it to a specific marker on a cargo ship in Easter Basin, San Fierro, where it can be lifted in place via a magnetic dockside crane, or simply driven up a ramp linking the dock to the deck of the ship if the vehicle is compact enough to be driven onto the ship.
