Lots of time, research and comparison went into my Dream Garage build (something I have been planning for years) and my Toy Collection (always changing, but stable at the moment), and I am extremely proud of both!
I don't believe that either are final, as I do get bored rather quickly, but I approach every purchase/lease - I lease my daily drivers - like I will own it for 10 years.
Currently, my Dream Garage is everything I have always wanted; its a dedicated place to work on projects without having to clean up everyday, while still being able to park my cars at night. There will always be a few things I wish my garage has, but those wishes can be for my next Dream Garage build!
