We have a large detached garage, which I really like. It's not heated, so the snow doesn't melt on the cars, but no scraping windows, etc. Detached means lower insurance premiums and less fire hazard. Garages are also a popular entry point for burglars. The PITA is when unloading groceries, etc.
The best thing about our garage is not the location, but the size. 30 feet deep and well over 20 feet wide, we can fit three cars plus lots of other stuff, but is still a "two car" garage from the street.
Bummer is the 18' wide single door when a replacement is due. They're pricey.
