Stop in for a cup of coffee

There were some tests that they did for Jeeps and trucks that were "confidential" and we were not allowed to talk about in public... The winter cold testing was insane!!!! (but I can't talk about that...)
I don't even know what kind of car, but we stored one in a freezer truck for someone when I worked at the cold storage. Not sure what the purpose was. That had to be around 1990. Was in there a month or more IIRC. I heard it wouldn't start when they got it out..
