According to cgrader low poly could be just about any model. Just do search with low-poly and 250k+ polycount filters applied. Here's some results:

https://www.cgtrader.com/3d-models/character-people/clothing/sneakers-1
https://www.cgtrader.com/3d-models/car/sport/lamborghini-aventador-la-police
And there's many more. Take a note that all those models has special low-poly badge applied, which means that those models are checked and approved by cgtrader staff, AFAIK. Why we need separate low poly models section then, is beyond my understanding.
