That's a great site! Thanks for sharing it -- I really like their map display. Beats Autolist by a wide margin. I bet I'll never remember the site name though.
This i3 was just listed today. It's a February build and has Harman Kardon audio -- AFAIK the only new 2021 in the US with HK. Wonder where it's been hiding all these months?

The HK-equipped one I bought in Texas in August had been on the showroom floor since February (January build). It wasn't listed on CarGurus; I think I found it on AutoTrader.com. I wonder if that's why it had been sitting for so long? This was right during the mini-frenzy surrounding the closing of the US order book and the loss of the HK option, when a few dealers were asking $5k markups.
