Try this, it may seem the same, i just tested it myself. It works fine for me:

pawn Код:

CMD:getcar(playerid, params[])
{
    new carid;
    if(sscanf(params, "i", carid)) return SendClientMessage(playerid, ~1, "USAGE: /getcar [carid]");
    if(carid > MAX_VEHICLES) return SendClientMessage(playerid, ~1, "That  vehicle does not exists.");
    new Float: gPos[3];
    GetPlayerPos(playerid, gPos[0], gPos[1], gPos[2]);
    SetVehiclePos(carid, gPos[0] + 2, gPos[1], gPos[2]);
    return 1;
}
