Dragonball UC Event: unfair

We pay 900 UC for the event. And at two points (character snd vehicle choice) we are bound to opt for Goban and Son Goku UAZ skin because it's mandatory for a bunch of missions important for points. I badly wanted Piccolo and Bulma's motorcycle. It's so unfair that you have to eventually spend more UC to SPIN and get it by chance. It sucks.
