[CAR]

I hope this works:

pawn Код:

dcmd_cardestroy(playerid,params[]) {
    if(IsPlayerCommandLevel(playerid,"cardestroy")) { // I named it cardestroy...
        if(!IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid,red,"ERROR: You must be in a vehicle.");
        SendCommandMessageToAdmins(playerid,"CARDESTROY");
        new string[256],name[24]; GetPlayerName(playerid,name,24);
        format(string,256,"You have destroyed your vehicle");
        SendClientMessage(playerid, red, string);
        return DestroyVehicle(GetPlayerVehicleID(playerid));
    } else return SendLevelErrorMessage(playerid,"carcolor");
}

But I don't know how your system works...
