Yes, Colin, thanks for the question. I'm going to answer this. So, as I think about new vehicle margins, there's a number of dynamics, I'll just very briefly touch on. You're right in terms of percentage margin. What you've seen since, let's take 2019 as is the pre-pandemic year, what you've seen since then and now is obviously a significant increase in ASP. And I don't -- even though I see ASP is moderating as we go forward as mix comes back into a more normalized level as OEMs continue to gradually increase their incentive to stimulate demand.
I don't see ASPs returning back to the 2019 level, which inherently, if you're able to hold, obviously, the percentage margin means from a dollar perspective on a per unit basis, we should and probably expect higher dollar margins than we saw pre-pandemic even if we return to that percentage margin that you mentioned at the beginning.
Obviously, as we transition as an industry into higher levels of electrified vehicles, we know from the impact that we saw in 2023 and still see in terms of TIN margin. And TIN margin for me is purely what's attributable to the vehicle, excluding everything else. TIN margin came under pressure, particularly in fully electrified vehicles as OEMs, dealers, all of us were trying to stimulate, take rates. That, to some extent, as I've mentioned, the balance at the beginning of my opening comments, I think, is why we're -- we are thinking favorably about that.
But that is a dynamic that will until they drive -- until all OEMs are able to drive the cost lower in those vehicles be an impact on our business. But what has changed is, if you look at the lease rates of electrified vehicles, that's doubled in the last 12 months and losing electrified vehicles, in my view, more balances the contribution to the ASP in the marketplace that the customers are happy or are more prepared to accept. So quite a lot in my answer, apologies. So that's kind of my thinking on new vehicles in total.
