I just confirmed with my sales adviser, it is still available for purchase and is in inventory. Model 3 performance, black, 18" aeros, $50,740. She also confirmed that it is without any of the Performance Upgrade Package.
She told me she sold 2 yesterday, including the one that was in inventory she quoted me yesterday afternoon.
I'm now waiting on my trade quote to see how underwater I'd be to trade my 8 week old LR AWD. I'm guessing I won't be able to make it work without taking a bath on it, but we'll see.
