Actually, I'm more particular about the undercarriage than the body itself. I usually throw something over the hood if it sits in the sun (black and Florida don't mix), and spray out the undercarriage after all off-road excursions.
I got lucky finding this one. It was from Arkansas, then lived most of its life in Louisiana (where I bought it). It also remained almost entirely stock it's whole life. So it was never subject to bad weather, salt, or hard-core off road abuse. Thus, what I got for $3,950 was a stock CJ in perfect condition. NO RUST! Ran like the dickens. I've just tried my best to keep it that way.
'82 CJ-7/360/727/D300/M.O.R.E. shackles and lots of ideas!
