For some background: I got my 5th gen SS Camaro in high school and it is in amazing mechanical and physical condition. I’ve stored it at my parents since graduation which was a pole barn with insulation and concrete floors, but now that I have my own place it’s time for me to move it there. The space is a detached pole barn garage with a concrete floor and sheet metal siding/roof. I’ve already went through and sealed up any holes along the bottom of the sheet metal and the ground as best as I can with expanding foam, so it is sealed up pretty well. My main concern is humidity in the summers (it can get up to around 105 F outside where I live) and during the winter it isn’t uncommon to see -5 F. This is a car I plan to keep my entire life so I want to keep it as pristine as possible. What are some things I should do to help keep it nice? Is that building in the summer going to cause damage to it from being so hot? It typically won’t be driven very often, maybe once or twice a month in the summer, and once the salt is down on the roads in the winter not at all. Thank you for any suggestions or advice!
First off does the building seem damp or have evidence of moisture and/or rodents able to get into it? Does it smell musty inside? If yes to any of those then either rectify the problem as best as possible, rodent repellents/traps around and inside the building for rodents, fix leaks but also make sure it can get air movement and dry out. Damp/wet building are more damaging to a car then just sitting outside.
Personally I would do nothing but try to take as best care of it as you can but drive the thing as much as reasonably possible when the salts not flying, honestly the best way to keep a car in mechanically good shape is to use it. Then during the winter if it’s a reasonably dry building, put a maintainer on the battery and call it a day, then give it a good bath in spring.
Temperatures won’t really hurt anything. Indoors will keep the sun from fading the paint. Biggest issue will be mice wanting to chew the tasty wires.

Lay a tarp on the ground and then setup the bubble, this is the best bang for the buck. Also moisture, use moisture absorbers if possible lots of them.
