Mercedes to charge subscription for more power

For $1200, mercedes will allow you to unlock the performance of your vehicle, roughly 20% boost. This is no mod, it's merely to unlock performance that is in the car when you bought it that they purposely disabled. Just one more reason I don't ever want to buy a mercedes.

Mercedes is charging $1,200 a year for faster acceleration
I look at it this way.........It's probably more cost effective to build all of the cars the same way when they are on the line. This way, I can purchase a base model (no options enabled) right off the lot as opposed to "taking" whatever they have in stock......Maybe options that I don't want.
