17:42 Yeah. Look, like you said my thoughts evolved on the need for us to have a captive finco, no. But they're certainly solidified. I view it as an important piece of the business for us going forward for our AutoNation USA stores. I think -- when I think about our business, one of the reasons why I wanted to slightly restructure it was to enable us to put in place the tools that AutoNation USA needs to be successful going forward. Obviously, on the franchise side, we have relationships with our OEMs, and that's slightly important, but we have a business that is in a growth phase. It will continue to grow. It's proven that the model is working, and it needs, in my view, to have the flexibility of a timed finco. That finco, like most successful fincos, will not be responsible for picking up the whole book. Naturally, you're going to remain in partnerships with people that have been supportive during your period of growth before, and I expect that to happen going forward. You will absolutely hear more on this subject as the year develops. But one of the things that we will do is I think, the group has always done, is not rush the purchase. 18:47 I think that there are opportunities in the market that may -- that are interesting at this moment in time. And as we find what is the right opportunity and the Board agrees with that, we'll make the appropriate move. In terms of our conversion rate on used, I can tell you it remains strong. At this moment in time, we are not seeing a drop off in terms of conversion. You can see from our CFS, our Customer Financial Services performance, that in fact, that's improving. It's been a strength of ours and continues to be a strength of ours. 19:17 So at this moment in time, what I can tell you is when I look at both the top level of inquiries and also some of the conversion rates by mix, we're not really seeing any dramatic shift except in the sub, I would say, $22,000 mark, where we are seeing a drop off of not raw inquiries, but really a drop-off of conversion, and that's more to do with inventory. As you know, that inventory is relatively tight across the industry, and we're seeing the same thing, but it's been more than supplemented by an increase in plus $40,000 inquiries. So did that help paint some color for you?
