As for prices, while demand would increase as a result of the tax credit (that's the intent, after all), the current prices don't allow that much headroom relative to the maximum MSRP (55K for sedans, 69K for SUVs). At this point, I'd expect overall inflation is more likely to significantly increase MSRP than TSLA harvesting tax credit $$$.

Below is a spreadsheet with my estimated delivery dates over time. The jump to October earlier this month was especially awesome.
