My goal in the game is "own all cars", and when reaching the 5 Mio M$ cap, I do not want to spend the M$ on anything else but cars. My thinking was that when owning all the F1 cars, an alternative M$ bonus in later F1 2020 events could give me the opportunity to buy other outstanding M$ cars, which where not available at the time I purchased the F1 cars, like the 2020 Nascars.
If there is no alternative M$ bonus instead of an F1 car, my strategy is/was moot and I lost the opportunity to upgrade some of the M$ cars.
BTW : since the start of the F1 2020 season, I farmed 22,5 Mio of M$.
