Personally I would do this with a bit of jQuery and an additional partial view. Your form could look like this:

        @Html.DropDownListFor(m => m.Make_Id, Model.MakeList, HeelpResources.DropdownlistMakeFirstRecord)





  

and then in your controller:

public ActionResult GetModels(int id)
{
   ViewBag.DdlModels = new SelectList(rep.GetModelsForCar(id), "Id", "Name");
   return PartialView();
}

and then just stick your drop down list in the GetModels partial view
