The max is 4M M$, so yes, decide which car you wan't to upgrade fully first and do some upgrades.

But my advice would be to atleast have a 2M M$ in reserve by the time of the next update. FM said they might introduce the M$ in other motorsport series also, so if they decide to introduce a new car in this series, in the next update, than we'll need that extra M$ for that car also, besides the next F1.
