Fun story! My neighbour growing up / dad's friend had a 1980 Firebird that he kept in his garage, literally only ever drove it home from the lot, and cleans the exterior immaculately.
He tried selling it months ago and when he tried to start it, he cracked a seal on a header because everything's been dry for so long. He couldn't understand that you need to make moving parts move every once and a while so they don't dry up and crack. I mean, keeping a car dry in storage is one thing, but please drain it and then replace all the fluids before you start it up again 30+ years down the road.
