edit build own new array [by hand]

  $result[] = $your_array['maruti suzuki'][0];   $result[] = $your_array['maruti suzuki'][1];   $result[] = $your_array['maruti suzuki'][2];   $result[] = $your_array['maruti suzuki'][5];   $result[] = $your_array['chevrolet'][0]; 

to random array use

 <?php    $res  = call_user_func_array('array_merge', $your_array);    $new = array_rand($res);    $result = array();    foreach($new $key) $result[] = $res[$key]; 

to random array , limit 5 use

 <?php    $res  = call_user_func_array('array_merge', $your_array);    $new = array_rand($res,5);    $result = array();    foreach($new $key) $result[] = $res[$key]; 

in $result random new array in case new keys!
