Good morning, Chris. We did try to be as transparent as we could in our prepared remarks. Yes, the fleet situation is ever evolving. If you think back to last year, it was really about removal of fleet. We canceled orders. We had the best-selling month in the history of our company in the month of August. And traditionally, if you think about how we manage our business day-to-day, we don't normally do that, right, because the peak period starts in the summer and then you hold on to cars and you try to leverage that volume and revenue opportunity. This year, it's a bit different. We came off probably one of the better per-unit fleet cost in our company's history, largely due to the COVID shutdowns that some of the OEMs had and the delay in inventories on both the dealership lots and used cars. And we took advantage of that. I would say that going out this year, we still see, as we saw in the fourth quarter, a pretty good used car market. That's -- it seems increasingly strong, I will say that. But we are getting our new cars in, and the new cars are important. When you think about fleet and fleet costs, it's not just how you buy them, but it's -- and how you sell them, and we've talked a lot about those in the past, buying cars with the right trim levels. People want to drive. And also they want to buy when we're done. I think it's also becoming more increasingly important, especially this year, as we cycle in new vehicles and we keep our rotation solid, because what ends up happening there, one of the key indicators of residual values is the mileage on cars. And as we get new cars in, that kind of tends to normalize. I see going forward the opportunity to sell car is solid. But you're right, the semiconductor thing which I mentioned earlier is going to have an impact on just new cars in general as well as, I believe, our industry. And we're working hard to mitigate any potential issues we might have. I will circle back to one touch point, however. If you go back to 2014, or maybe even 2017, our industry was hit with a tremendous amount of recalls. Hundreds of thousands of cars, 1/3, if I recall, maybe in the third quarter of '17, of our entire fleet was under recall hold. And we were able to manage through that. So I have confidence in our team. Do I think there might be disruption due to this travel, due to the semiconductor thing? Yes. But as it stands right now, I'm comfortable with our fleet levels to both sell if we need to, or maximize our volume as it comes.
