#In-appPurchases

Tesla pricing is about as predictable as the winning lottery numbers. This year it added numerous surprise fees onto its supercharging network and rearranged the pricing structure for its Model S sedan more times than I can remember. Most recently, the company increased the price of its base Model S 60 from $66,000 to $68,000 with an $8,500 software update that unlocks the battery’s full potential — since the 60 is just a 75 that has been digitally neutered and rebadged.

In some instances, almost 30 percent of the value of the vehicle can be unlocked through in-car purchases. There are all manner of software-upgradable items but keeping up with their pricing is nearly impossible, especially when Tesla doesn’t actively announce those changes.
