My experience in the Great Recession time was that the car I was buying was very well priced, but consequently my trade was not, so it all kind of evened out. I suppose the real deal is if you are buying without a trade, and even then it probably depends on the dealer. It'll be interesting to see if these high-volume mega dealers or the smaller guys are hit harder. The stuff sold in the finance office I'm sure balances out selling at a low price, but what happens when all the music stops? I'd assume the shell game gets pretty tough with everything going on and high overhead and market and so on...
If you want a very fascinating (yet sad) read, search the story of Reagor-Dykes Ford in Lubbock, TX. $40M fraud with Ford Credit on floor plan shell games.
Ford Motor Credit filed additional documents with the bankruptcy court Friday morning, claiming this may be one of the largest floor-plan financing frauds in the history of the United States.

I bought two 200s and the buying process for each was night and day. First one ('15) was priced comically high at a small BMW dealer in Ohio. The initial round of negotiations left us $15k(!!) apart, they didn't seem serious so I politely declined. Lots of statements about how rare and valuable despite it being for sale for 7 months and counting... about a week later the emails started coming with price drops. After about two weeks we settled on a deal at $1k higher than my offer. Of course when I got there out came the foursquare and the paint protection and the nonsense.
The next 200 ('17) I got in September of '18 was from a large volume GMC dealer locally listed without a price because it just came in and they hadn't even added pictures to the website. I called to inquire and their initial offer was spot on for what I would have considered. I didn't even counter and the deal was done and out the door in 90 minutes with friendly, polite, and non-pushy sale and F&I guys.
I'd guess that if you're the #1 LC dealer in the US you probably have a good command of the market and can probably get a bit of a premium knowing that it will be inspected and reconditioned appropriately. But generally speaking, it's very hit or miss with dealers selling them just like it's very hit or miss finding a dealer who will correctly work on them.
