CarMax

Yes

The indoor space is large, and really well ventilated. The cars are cleaned in between test drives. Employees all wear masks and they have a system where the desks where they sit down with you to go over everything is cleaned in between visitors. The only issue I worried about while there was the door between the garage area and the business personnel meeting area (when buying a car), since that door is not automatic open. But, that is going to be a lot less of an issue in warmer months, as well as the fact that you can just use sanitizer on hands after going through there (if you do, even).

Yes sixty day warranty with option to buy additional warranty many options available. 7 day return policy also is nice

You need to have payment method... and a car insurance valed driver license or ID ...

No they don't

I'm not sure, butter to ask this question to the carmax associates.

They didn't offer me much for my trade in so I sold it on my own.

If you want a quote on your vehicle you will need to take it to their store. They'll give you a price that's good for about 5 days and not dependant on you buying a car from them. Asking questions about a place on Google Maps is not a way to contact the place, but rather ask questions of others who have been there.
