I'm about to acquire a '91 that has been sitting for six months. Cosmetically excellent, obscenely low price, and the 4-wheel air ride suspension is flat. The previous owner rode it that way, actually putting smaller tires on the front and bottoming out the transmission pan (ouch!). However, he insists the bags are intact. So I want to have it inspected by the dealer before I decide whether to salvage the system or replace it with air shocks.
And yes, I'm going to have the transmission flushed and serviced, since he was not using the correct fluid. This car deserves better treatment than it's been getting.
This is my first foray into modern Imperialism. I have read the thread archives regarding this system and the rest of the 91-93 pages, but if anybody has any other thoughts please feel free to weigh in.
