Comparing prefab vs custom garages for my Middletown home

I’m trying to decide between a prefabricated garage and a custom-built one for my home. I really need extra storage space and a place to park my car, but I’m not sure which option makes the most sense long-term. Custom feels like it would perfectly fit my property, but prefab sounds quicker and potentially more affordable. Has anyone gone through this decision process? What were your experiences, and what factors helped you choose?
