He squirmed because a body lift is a pain in are arse to install. The lift itself is not expensive. The labor is what is gonna cost so much. I put a 3" body lift on my TJ, and it was awful to install. You have to extend fuel filler hose, transmission linkage, just an overall pain. May not have to do all of that with a 1", not sure. Point to my story, I would take the advise of the shop. 35's are spot on with a 2.5" lift. I don't know why you wouldn't be happy with 35's on a 3"er.
Do not perform any mod for looks alone, mod for function. I promise you if you plan your mods to improve function, you will have a Jeep that "looks" the way you want.
