LOL--can we get this as a forum badge or a t-shirt?
True, but Tesla has also not shied away from using different parts for performance models--fore example the only difference between the original S and P models was the inverter. Because the drivetrain is modular, the cost of two options is reasonable, especially given the extra revenue/margin the upgrade generates.
I am also not sure the prices are the same, when I look at the EPC, for the LR, I see ASY,3DUR,MOSFET-HC (which I assume translates to 3 Drive Unit Rear) for $2.5K while on the Plaid, I see REAR DRIVE UNIT - TOP LEVEL ASY, PLAID for $9K?
