However, there is one in the 12 Cyl Slam series. If you start out in the series in Tier 1 using the McLaren and work your way in order through the series, you will be eventually be offered the discount on both the 16.4 and the Sport Vitesse. There is one for the Zenith Series, if you grabbed the Zonda R for free back in February 28th or won the LaFerrari or Veyron 16.4 GSV in their respective LTS.
