Seems much closer in price to your parent's list than your list, though the reality is it's somewhere in the middle:

    3 Series - $33,450 (-34,550)
    C Class - $39,500 (-28,500)
    5 Series - $51,200 (-16,800)
    Model S - $68,000
    6 Series - $77,600 (+9,600)
    Porsche Panamera - $78,100 (+10,100)
    7 Series - $81,500 (+13,500)
    S Class - $96,600 (+28,600)

Edit: With the US federal tax credit of $7,500, it comes down closer to the bottom list, but still in the middle.

Being competitors is not just a question of price. How many people buying a Tesla have considered buying a Mercedes S Class? How many people buying a Mercedes S Class have considered buying a Tesla?

If you make the same comparison for the EU the differences will be much (much!) larger due to various taxes. Especially for cars with larger displacements. In NL for instance the cheapest Panamera is 109000 Euro.

GP is also using the same marketing trick used by Apple. Sell huge numbers of an anemic product lineup and trumpet those figures against single models from market leaders whose aggregate sales across 20 models dwarf sales of 2 models from Tesla/Apple.

He should have used the E-Class/5-Series/A6 segment, not one below. Then the price difference after incentives is a bit over 10k. While going up market the difference can be more than twice that much.
