I think I might be the only person on the planet that parks 3 vehicles in a 3-car garage. Granted, being oversized helps, but that's my daughter's Escape, my Suburban, and my crew cab Sierra Denali.
Upside - while I've never done any type of rust preventative, the Suburban's frame is still mostly black and it has zero body rust. It's an 08 with 250k miles, and has spent its entire life in MI and IN. But it's been garaged religiously for the 11 years I've owned it.
I looked hard for a 3 car garage before we got this house. I just couldn't find anything. I did get out bid for one that had a 2nd detached 2 car that would have been nice. but it was also a 45min drive from work but I'd have taken it haha
