I got those Husky mats (the above one is specifically for the manual trans) and while not perfect I’m happy. I had them on my CX-5 too.

Otherwise.. congrats on the new Corolla! If it’s hot where you are, I’d think about tint. I have a dash cam in all of our cars (I installed one the night I brought my Corolla home, I recommend the Aukey DR02 on Amazon). LED license plate lights and interior lighting is another thing I do anytime we buy a new car. Lastly I’d check and change the cabin air filter.. another thing I change immediately if it’s a used car.

Enjoy the new ride! 👍🏻
