Server economy ideas?

[Snow]

you could increase the price of gasoline, a system of upgrading cars, buying factions, selling air vehicles, buying items such as phones, mp3, gps, drinks, food, etc, drugs too, it is best not to give an excessive amount of money to the player because that tends to bore, you can also make a bail system that if the player that under prison someone can pay his bail. Well those are my ideas but I'm sure there are many more things, I'm more of roleplay servers but I hope you find them useful.

Uh well, I see where's that coming from. Since its a freeroam server, vehicles can be spawned easily with a command without having to buy them. Therefore, selling vehicles will end up generating excessive cash. Also there's no concept of factions and prison neither I see any point of adding them. That will definitely ruin the fun.
