Talk:McLaren Mercedes MP4-25 (Championship)/@comment-84.140.112.208-20170119110600

Is it possible to win the mp425 during its championship...with JUST 10-0-10-0 pro-upgrades & WITHOUT extratanks ?

(Btw, how difficult is to get the engine-cards needed for mp425 from the challenges during the mp425-championship ?...are there enough engine-cards in those boxes, or just 1 in a box ?............& yes, if u know->how many engine-cards are in the boxes that we can buy with tokens?)
