I'm in the 'ventilation is key' camp.
When I was looking to buy years back, I viewed what appeared to be an immaculately maintained '09 GTS. 1 owner, full Maserati history, absolutely immaculate inside and out, AND garaged EVERY night since new. When I looked underneath I was horrified! It looked like an 80's Ford. Rust everywhere.
On talking to the owner, he was completely oblivious to the fact that putting away a damp or wet car might be the wrong thing to do. He just assumed garaging was for the best.
I do garage mine, but only if I know its dry. Its a timber garage/ small barn so there can be a bit draft anyway. It used to stay on the drive otherwise. I couple of years ago I fitted an electric roller door, so I could keep it open a little to increase the air circulating if required.
I have just built a new "cart lodge" (otherwise known as car port lol), so now I have somewhere under cover but fully ventilated to keep the car until its properly dry, before putting it away for any length of time, which is ideal.
Excuse the current state of the house, its a work in progress lol
