Retrieving the values from my form

I'm trying to retrieve the values of a form. Is this a good way to get them back to get through my DAL?

<div id="myModal_Veiculos" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <form id="Cad_Veiculos">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
            <h3>Cadasto de Clientes</h3>
        </div>
        <div class="modal-body">
                <label>Modelo </label><input type="text" name="modelo" id="modelo" />
                <label>Placa </label><input type="text" id="placa" name="placa" />
                <label>Quilometragem </label><input type="text" id="quilometragem" name="quilometragem" />
                <label>Cor </label><input type="text" name="cor" id="cor" />
                <label>Tipo </label><input type="text" name="tipo" id="tipo" />
                <label>Ano </label><input type="text" name="ano" id="ano" />
                <label>Chassi </label><input type="text" name="chassi" id="chassi" />
        </div>
        <div class="modal-footer">
            <button class="btn" data-dismiss="modal" aria-hidden="true">Fechar</button>
            <Button class="btn btn-primary" onclick="button1_cad_veiculo">Salvar</Button>
        </div>
        </form>
    </div>

Retrieving form's values

protected void button1_cad_veiculo(object sender, EventArgs e)
{
    Veiculo vl = new Veiculo();

    vl.Modelo1 = Request.Form["modelo"];
    vl.Quilometragem1 = Request.Form["quilometragem"];
    vl.Placa = Request.Form["placa"];
    vl.Cor = Request.Form["cor"];
    vl.Chassi = Request.Form["chassi"];
    vl.Tipo = Request.Form["tipo"];

    VeiculoDAL.cadastra(vl);
}
