I agree with bank limit should be increased. I also think that the money should be more difficult to make and more ways to lose it.
After that, special shop item prices should be decreased, race hosting cash limit should be decreased/removed (this allows players to just race if they want [attract racers]) so players who aren't into weapon buying/deathmatch can have something they want to purchase made more accessible.
/agree, you shouldn't need cash to make races, just another change
my suggestion:
If you want to create a race up to cash limit say(500k), then you dont need any cash for it, but...
If you want to create an extra ordinary race with more prizes then u need to add the extra money yourself!
And also that car export isn't really doing great for server! Maybe we need to increase the cash we can get by export say like 100k or something, this way money flow will increase, and if possible we can add blips which shows the car you need to export (say infernus, you can export only 1 infernus not any infernus), and also the car export announcement color should be changed to red, to show more emphasis!
