Which car is the best ?

Hey guys . I have an account with 2500 sb from the event + level up . Which car should I buy , which one is the best ?

Lamborghini Aventador
Pagani Zonda Cinque
Koenigsegg Agera

I choose Zonda. Agera is feel like a soap on the street. McLaren will still be a problem to win against it. Aventador ...is like all the others Lambo's but more fast.

:) Thanks
