Sure, so first of all, we didn't try that breakout, so we don't tend to provide at here. I think it's easy to understand our rationale there. Going back in time to our analysts data, you reference, at that time, we were selling on the order of a core as many cars as we're selling today, our GPU was on the order of half, maybe even less than what it is today. And I think our EBITDA five 10, or 15 points worse. And so at that time, we were trying to provide pretty detailed walks for our investors, they could understand how those buildups would occur over time. I think, as we've matured, and as we've seen a lot of progress in many of those different line items. And I think, the market in general has a much better understanding of how the things progress, we're just kind of simplifying our reporting and kind of aligning more closely with industry standard. And so we don't tend to kind of break it out at that level of detail going forward. That said, I think it's not hard to infer the general areas that it's in, as you pointed to, and that general area is very exciting. And it's very strong compared to what we initially outlined at that analyst day, in 2018. So I think there's a couple reasons for that, some of them are fundamental and sustainable, I think we've really done a pretty good job with that business so we've made a lot of fundamental progress in terms of the way that we're able to assess credit risk and price, credit risk, and the way that we're able to monetize our finance platform. So there are a lot of things that we've done there that we're proud of. And we think that there's probably some additional fundamental value that we can unlock. I think we're also in something of a unique environment, you know, early in the pandemic, we tightened credit pretty dramatically, we've held credit tighter than probably would be the norm of almost constant. We've generally over kind of the last several quarters been in a very low interest rate environment. So that's helpful. So there are a couple things that aren't necessarily persistent across time. But we still think that there's progress to be made there. And then in the rest of other we think that there's progress to be made in our other existing items, we think there's progress to be made by adding additional items as well over time. So we think that that's, you'll want to have several success stories relative to our long-term model that we that we put out in 2018. And we think that gives us a lot of flexibility going forward.
