Here are my pros and cons of the air suspension (from my fairly uneducated thought on the matter):
-Slightly improved aerodynamics (3-5%?....rough guess)
-Improved capability for getting in and out of steep driveways
-Increased cost ($1500)
-decreased reliability...more to go wrong.
As I understand it, air suspension systems can be fairly complex, and could be one of the more unreliable Parts of the Model S.
So what do you think? Is the air suspension worth it? Why or why not?
