For those who are grinding (like me) after the second difficulty shift, the cars needs higher rank.. For Lamborghini Estoque upgrade, I used 2 Free Class B upgrades to increase Level 4 & Level 5 Top Speed. I used one Free Class B upgrade from the first reward car Lamborghini Gallardo Mastery challenge 5 the other I used from mastery of some other car I don't remember the name now.

This saved me 7,00,000 of credits for upgrading Lamborghini Estoque and I am confident I will be getting Estoque by reaching 42500 points so I used those 2 free upgrades for class B
