                header ( "Location: http://www.exampledomain/send.php" );
            } else {

Use the same if to all script:

<?php

if (isset($_POST['submit'])) {

$car_marke = $_POST['Marke'];
$car_modell = $_POST['Modell'];
$car_vorname = $_POST['Vorname'];
$car_name = $_POST['Name'];
$car_adresse = $_POST['Adresse'];
$car_plz = $_POST['PLZ/Ort'];
$car_telefon = $_POST['Telefon'];
$car_email = $_POST['Email'];
$car_bemerkungen = $_POST['Bemerkungen'];

$from = 'test@gmail.com';  
$to = 'test@gmail.com'; 
$subject = 'Formular';

   $body = "Marke: $car_marke\n Modell: $car_modell\n 
Vorname: $car_vorname\n Name: $car_name\n Adresse: $car_adresse\n 
PLZ/Ort: $car_plz\n    E-Mail: $car_email\n Telefon: $car_telefon\n Bemerkungen: $car_bemerkungen\n";



   if (mail ($to, $subject, $body, $from)) { 
    mail ($from, $subject, $body, $to) 
    header("Location: http://www.exampledomain/send.php");
    } else { 
      echo '<p>Oops! An error occurred. Try sending your message again.</p>'; 
      }
     }
     ?>
