just the underbody and you can check the trunk under the plastic trim. That's a growth spot. If I'm buying a LC I would consider shipping it from a state that did not have salt on the streets.
Save as much as money as possible so you can upgrade suspension, change LED headlights, change wheels/tires, change interior bulbs, tint all windows, wind deflectors, sliders. I put a push bar and a rear chin bar to stop minor fender benders (I like going high speeds so I didn't go with bull bar). If you want you can put 3m protection film on the paint or wait and put on a wrap.
