Are you asking for help, or for making script for you?
It makes difference.

Altought I shouldn't, I decided to make very simple script, which should work as you wrote in your post.
I don't know if it's working as I havent tested it.

Enjoy.

#define MAX_GIVEN_VEHICLES 100 // How many vehicles can admin spawn

new vehArray[MAX_VEHICLES]; // Array used for 'deletecars'
new Vehicles; // Integer holding how many cars has been spawned

new ppveh[MAX_PLAYERS]; // For /givecar

COMMAND:givecar(playerid, params[])
{
    if(!IsPlayerAdmin(playerid))
    {
        return 0; // Return 0, so that if player is not RCON admin he will get Unknown Command message.
    }

    new forplayer, carid;
    if(sscanf(params, "ui", forplayer, carid))
    {
        SendClientMessage(playerid, 0xFFFFFFFF, "error: Type /givecar [id/PartOfName] [CarId]");
        return 1;
    }

    if(carid < 400 || carid > 611)
    {
        SendClientMessage(playerid, 0xFFFFFFFF, "error: Wrong vehicle id.");
        return 1;
    }
    
    if(forplayer == INVALID_PLAYER_ID || !IsPlayerConnecter(playerid))
    {
        SendClientMessage(playerid, 0xFFFFFFFF, "error: This player is not connected.");
        return 1;
    }
    
    if(vehicles > MAX_GIVEN_VEHICLES)
    {
        SendClientMessage(playerid, 0xFFFFFFFF, "error: You cant spawn anymore vehicles.");
        return 1;
    }
    
    new
        Float:Pos[4]
    ;
    
    GetPlayerPos(forplayer, Pos[0], Pos[1], Pos[2]);
    GetPlayerFacingAngle(forplayer, Pos[3]);
    
    if(IsPlayerInAnyVehicle(forplayer)){ .
        new tmp_vid;
        tmp_vid = GetPlayerVehicleID(forplayer);
        
        if(ppveh[forplayer] == tmp_vid) // if player is in vehicle which has been given to him by admin (using /givecar command, ofc)
        {
            RemovePlayerFromVehicle(forplayer);
            DestroyVehicle(tmp_vid);
            Vehicles--;
        }
        else    // if not.. respawn vehicle.
        {
            RemovePlayerFromVehicle(forplayer);
            SetVehicleToRespawn(tmp_vid);
        }
    }
    
    ppveh[forplayer] = CreateVehicle(carid, Pos[0], Pos[1], Pos[2], Pos[3], -1, -1, -1);
    PutPlayerInVehicle(playerid, ppveh[forplayer], 0);
    
    new tmp_vid;
    GetPlayerVehicleID(tmp_vid);
    vehArray[tmp_vid] = 1;
    Vehicles++;
    return 1;
    
}

COMMAND:deletecars(playerid, params[])
{
    if(!IsPlayerAdmin(playerid))
    {
        return 0; // Return 0, so that if player is not RCON admin he will get Unknown Command message.
    }

    for(new i = 0; i != MAX_VEHICLES; i++)
    {
        if(vehArray[i] == 1)
        {
            if(IsPlayerInVehicle(playerid, i){
                RemovePlayerFromVehicle(playerid);
            }
        DestroyVehicle(i);
    }

    return 1;
}

There are also some differer ways to do such commands, but.. Figure them on your own :P
