I realize there has been many threads about air suspension reliability but none answered the questions I will pose. Because I am a professional mechanic and I like to keep things reliable and simple, I am tempted to avoid the air suspension. I may want to keep this car long term. Standard suspension is very simple, and easy to repair(rarely needs repair)/ modify. Air suspension will likely need replacement or repair at some point and the price will be much more than the $1500 you are now spending for the option. Some amounts I have seen people pay are in the thousands of dollars for repair. I would expect/hope, though we can not try it now, that Telsa will do a very nice job designing a traditional suspension.
I found this excerpt on the tesla club site:
Normal height = 6”
High Level 1 = 0.90” taller; When the vehicle accelerates above 19 mph, the clearance adjusts back to Normal height.
High level 2 = 1.3” above Standard and can be used for ascending a steep driveway or fording deep snow. Clearance reverts to High Level 1 above 10 mph.
Low Level = 0.79” under Standard; Active Air Suspension will automatically lower the vehicle for highway driving to improve aerodynamics. Low Level is also accessible from the touchscreen for loading/unloading of passengers. When the vehicle begins driving the clearance adjusts back to Normal height.
I must finalize my S this week. I like the low height the car looks in all the pictures I see.. My QUESTION is this to you whom already have the car: When the car is parked is it automatically at "low level"? At normal around town speeds, is the car adjusting itself back to "normal" level? Can a person adjust the car to "low" at around town speeds or only at hwy speeds? Would you say the usual pics I see of the S driving on the road are "normal" height?
