If mine lasts that long, people will be making fun of it because it requires a driver.

Since we're on the subject of all things maintenance, my current TTS makes a pretty regular noise that I'm attributing to the air suspension, almost reminds me of a bed squeaking, dirty mind that I have. Seems to be front and back. I haven't given it a lot of consideration assuming whatever it is will go when it goes. Is it the air suspension pumping a lot to make up for a leak or something? Prognosis and repair cost?
