Filtering, N+1 problem, paginate

Hello,

I am working on result display page and have problem with filters.

Problem1 I want to display all possible makes and models + display how many results we have.

Question1 How can I avoid duplicating query? In my understanding I am not able to use the same result query to get possible makes and models because it have pagination and it shows me results only for this page (10 results)

Problem2 (solved) Close to every single record I want to display 1 photo if it have. I created method thumb() in ad model. but I am getting there N+1 problem

select * from `photos` where `photos`.`ad_id` = '30' and `photos`.`ad_id` is not null and `type_id` = '2' limit 1

Models:

//Ad model
    public function owner()
    {
        return $this->belongsTo(User::class, 'user_id');
    }

    public function car()
    {
        return $this->hasOne(Car::class);
    }

    public function bike()
    {
        return $this->hasOne(Bike::class);
    }

    public function photos()
    {
        return $this->hasMany(Photo::class);
    }

   public function thumb()
    {
        if (count($this->photos)) {
            return $this->photos()->where('type_id', 2)->first()->link;
        }

        return 'images/no-image.jpg';
    }

// Car model
    public function ad()
    {
        return $this->belongsTo(Ad::class);
    }

    public function make()
    {
        return $this->belongsTo(Make::class);
    }
    public function model()
    {
        return $this->belongsTo(Vmodel::class);
    }

Controller:

$vehicles = new Ad;

        $vehicles = $vehicles
                ->with('car','car.make','car.model','photos')
                ->join('cars','cars.ad_id','=','ads.id')
                ->where('status', 1)
                ->where('blocked', 0)
                ->where('confirmed', 1)
                ->where('paid', 1)
                ->whereHas('car');

        if (request()->has('make')) {
            $vehicles = $vehicles->whereHas('car',function($q) {
                $q->where('make_id',request('make'));
            });

        }

        if (request()->has('model')) {
            $vehicles = $vehicles->whereHas('car',function($q) {
                $q->where('model_id',request('model'));
            });

        }

        if (request()->has('sort')) {
            $vehicles = $vehicles->orderBy('ads.created_at',request('sort'));

        }

        if (request()->has('paginate')) {
            $vehicles = $vehicles->paginate(request('paginate'));

        }else {
            $vehicles = $vehicles->paginate(10);
        }

        $vehicles = $vehicles->appends([
            'sort' => request('sort'),
            'paginate' => request('paginate')
        ]);

Thank you for help!
