Firstly find the pos using https://sampwiki.blast.hk/wiki/Strfind . Then delete the veh part using https://sampwiki.blast.hk/wiki/Strdel . Then we will insert the right $veh thing using https://sampwiki.blast.hk/wiki/Strins. Also, Nice copying crazybobs .

EDIT (Example):

pawn Код:

public OnPlayerText(playerid, text[])
{
  new Check = strfind(text, "$veh");
  if(Check != -1)
  {
    strdel(text, Check, Check + 3);
    new Str[56];
    format(Str, sizeof(Str), "%s", /*VehicleNamesList*/);
    strins(text,str, Check);
  }
  return 1;
}
