Waw, good job.
Lots of commands tho.
I gotta view your codes and check for bugs (if theres any) xD
Edit: You can improve your loop players code like that.

PHP Code:

#define LOOP_PLAYERS(%0) \
        for(new %0 = GetPlayerPoolSize(); %0 > -1, IsPlayerConnected(%0); %0--) 


No need to create 2 variables
Also, replace the loop in respawncars command to this

PHP Code:

for(new cars = GetVehiclePoolSize(); cars > -1; cars--) 


if someone got 500 vehicle in his server, no need to loop the MAX_VEHICLES, because MAX_VEHICLES = 2000.
Also no need to use this

PHP Code:

SetVehicleHealth(GetPlayerVehicleID(playerid), 1000.0); 


after using RepairVehicle(vehid); because it sets veh health to 1000 already.
In your cc command (clearchat)
No need to use

PHP Code:

for(new i; i < 250; i++) 


because the chatbox gets only last 50 lines so just use this

PHP Code:

for(new i = 50; i > -1; i--)
