Make a global variable for those vehicle the player has created:

pawn Код:

new TmpVehicle[MAX_PLAYERS];

pawn Код:

...
if(strcmp(cmd, "/v", true) == 0)

    if(PlayerInfo[playerid][pAdmin] < 2) return DenyMessage(playerid, 2);
    tmp = strtok(cmdtext, idx);
    if(!strlen(tmp)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /v [carid] [color] [color]");
