Sooo I live in New Mexico and drive over brutal roads for a living. My poor Aero doesn't like the conditions. I was thinking of getting a Grand Cherokee but then it dawned on me to pick up a 900 and maybe do a lil' off road suspension set up on it - Bilsteins, etc. Anyone gone that route before? Don't really need to lift it up I think, just maybe some stiff shocks and A/T tires.
