How to make an interesting gameplay? (Forza Horizon 4)

Forza Horizon is undoubtedly a masterpiece, especially the fourth part, he played it, it's just a game about cars.
But for me there is one big minus is the lack of any motivation to make money, because since the first minutes of the game, you just fill up with cars, just like you three cars, here's another two, and another, and another.... and so much money that you simply are not looking to buy them (playing in the license, cheats no use if that).
And I would like to give you at the beginning of one car, and you jerk off to it some time, improve her money, invest it, and slowly saving up for a new car, and when accumulated, it is still thought about what car to take, because money is only enough for one - not that I'm lacking in Forze.
And when you have early in the game for 20 cars, and another 30 you can effortlessly buy (I'm figuratively writing), then lost all the value of these machines, they become routine and perceived as self - bought one, drove around, got bored, bought another and so on.
Like and they worked great, and physics, management, and day, but the glut of cars, not in terms of a large fleet, namely when you have a lot, kills all incentive to play and earn on them.
Tell me how you're feeling?
