Best Website for Vehicles for sale/list for sale?

What's everyone's opinion on the best place to search for used vehicles & list a vehicle for private sale?

I've tried the usual Autotrader, but it seems fewer dealerships & private sellers are using Autotrader compared to years past. CarGurus.com seems to have mostly small or "buy here" dealerships (at least in my area) and few larger dealerships. Short of searching a bunch of sites, is there a website that taken over as "best in breed" for online searching?

I'm thinking about listing my Tundra for private sale and eventually buying another used truck, probably a 3rd Gen Taco.

 

When I sold my car about a year ago, I listed it on Auto Trader and Kijiji (kind of like the Canadian version of Craigslist) and then a few days later, I got my wife to list it on Facebook Marketplace for me since I don't have FB. The person I ended up selling it to found it through Marketplace (he messaged my wife on FB and she gave him my number so he could text me).

Interestingly, I got only scammers on AT and Kijiji until I listed it on FB Marketplace then I suddenly started getting legitimate interest on those other two sites as well at the same time. Not sure if that's coincidence or what.

I don't buy used vehicles but we found our travel trailer on Marketplace too.

 

I've sold several vehicles on Facebook Marketplace. I've also sold on Craigslist before Marketplace was as big as it is today. Not a big Facebooker by any means, rarely ever on it, unless I need to use Marketplace.
