    So , here is the result.

    Relation in model Customer.php

    public function cars() { return $this->belongsToMany('App\Car','car_customer','car_id','customer_id'); }

    Query to get all customers with N cars.

     $userInput = 2;
     $data = Customer::with('cars')
                    ->withCount('cars')
                    ->has('cars', '<', $userInput)
                    ->orderBy('cars_count', 'desc')
                    ->get();
    

    $userInput is your 'N'
