Now that I'm able to price-out my Model 3, I have to make a decision about the FSD capability. There is no doubt that I want it, but currently only the Enhanced AP is active and the FSD isn't available yet. I know that I will save some money by getting the FSD capability now, and it will be convenient rolling it into my car loan. However, I also want to keep my payments as low as possible. I'm wondering if it makes sense to just get the Enhanced AP now and then activate the FSD later once it is actually needed?
