Well, we have variable sales comp sales growth has come down, obviously, the compensation would come down. And I think that, when we look at cost reductions, what we're seeing is by reducing our sales force, we've been left with the best salespeople, what we're getting is better productivity from a sales perspective. And quite honestly, that's helped us not only from a growth perspective, but quality of sale and other things, the same thing. We're getting productivity from mechanics. But I see personnel being pretty solid. We have 3%, which is about 600 people still out. John, I think we'll see probably a good portion of those come back, but there'll be time back as we need them. But I think on the major pieces we've got back, so I would say personnel will say pretty much solid, I think from an advertising perspective, I think that we will be able to continue to have that at a lower rate as we use our digital tools. And vehicle maintenance is a big area, because based on our ability to get deal cars through the shop quicker, with our more experienced people, less loaner cars, less vehicle maintenance, better quality, less policy for our customers. And then again, our T&E when you think about travel and entertainment using the Zoom and what we're all using today to connect the reduce that significantly, I'm not sure what it was in the quarter, but I know it was several million dollars. So that should be able to give us some confidence that we can move the SG&A in an area where it is. And I think right now it's 67. We looked at a model, if we took $500 to $1,000 off the gross profit, it would move us probably into the 70%, 71% or 72%. So as we look at the model, I think that we're pretty strong on where we're going to be on our cost reduction, as it affects SG&A.
