I picked up a FT about a year ago that came from someone keeping it in a garage close to the coast. It had a lot of corrosion, some planking, and such. Nothing major but I wouldn't want to risk having those issues on a new expensive Stern. It might take years to see those problems so maybe it's no big deal if you trade out games every year or so. I just think it would be miserable playing pins in a hot garage 5-6 months out of the year. Plus you have all kinds of bugs and critters that would love to make a pin their home. If I had to put pins in my garage, I would definitely look into insulating it better, having some temperature control, and a plan to keep bugs out.
