Hi I am in Chicago and recently purchaced a G35S. I know its not many dealers to chose from here but how friendly are the service dept. In Particular, Lisle, Orland Park, Mid Town, and Glenview. I am looking to get thge TCM and maybe a sports suspension installed there.

if anyone has experience with this please e-mail it to him rather than spell it out for the world to see. Infiniti corporate reads these boards and they may frown on those dealers "who look the other way" on mods...

oh come on!
