How can I exclude Carvana from my search results?

You could only look a private sales. I have not seen a Carvana filter.

Thank you for the advice! What I do now is filter by "Closest First," which jumbles up the good/bad deals, but places the Carvana results at the end. And that really underscores the oversaturation of their stuff--e.g. I'll get 10 pages of results, and near the bottom of the first page I start seeing Carvana. For the next nine pages, it's nothing but Carvana

You found a solution! I have never seen a car search filter that allows you to exclude certain terms but it could be handy.

I have found some Carvana vehicles that are tempting.

Carvana is a scam which is why people want to filter it. They DO NOT HAVE THE CARS they claim to have. Cargurus, if they are reputable, need to provide filters for that fact.

Under "Filters", select "search in description" and in your search field use "-carvana" and they will be omitted. Voila!

Carvana needs there own search on here. I can't even use this website anymore..
