Career series such as Vanguard Challenge only unlock when you go through all the previous career series. Bonus series such as 12+ Cyl Slam normally unlock when a car that is part of the bonus series is won.

Vanguard Challenge would not unlock because the Bugatti Veyron 16.4 Grand Sport Vitesse is not part of this serie. Zenith Series is, but it will not unlock if you haven't gone through Spirit Of Ferrari.
