I personally enjoy only making 20-30k (or less) per race. Gives you more of a challenge and makes you work for the cars you want. With the introduction of the seasonals and large payouts, everyone and their bother has nearly every car. Kinda defeats the purpose of the large variety of cars to compete against. There is never a "surprise" car that you race against. Not to mention your garage is no more diverse than the other guy/gals garage.
When I first started the game was the most fun as I actually had to "work" for my little Skyline R34 and F430. Now I can buy multimillion $ cars like its nothing. I do enjoy and want them to keep the seasonals...but want the payouts to be less. LOL and I dont even grind.... IMO obviously
