Linking the Gameboy Advance version of Hot Wheels Velocity X to the Gamecube version of the same name rewards the player with two exclusive vehicles in the GBA version… that is, if you can actually figure out how to connect both games.
The worst part, the GBA version lacks a save feature and the master unlock-all code omits these linked cars. Meaning, you’ll need to link to the Cube version each time.
