Laravel 5 - How to pass multiple parameter in GET route?

Can anyone please help me to pass multiple parameters in GET method, I have following codes -

in blade -

 @if(!isset($model->id_car_type))
     <a class="btn btn-search-red" href="">Select</a>
 @else
     <a class="btn btn-search-red" href="">Select</a>
 @endif

In route -

Route::get('/model/{make}/{year}/{niceName}/{type?}', 'GeneralController@trimShowByNiceName')->name('frontend.model');

But it is throwing error -

Missing required parameters for [Route: frontend.model] [URI: model/make/{make}/year/{year}/niceName/{niceName}/{type?}]
