Yeah sales are down 50% Y-Y, but Model S ended 2019 with 22% market share of large luxury sedans. And that's with the supply of Model 3's plentiful enough now to take away customers who just want a decent EV, and the tax rebate down within range of typical dealer discounts of the other brands. So a pretty level playing field, and S sales seem to have leveled off for the past 6 months, maybe even inching back up. #2 was S-class (19%) and #3 was 7-series (14%). Overall though sales in this category are down 37% compared to the peak in 2016. Source: goodcarbadcar.net
