I have a three car garage, with enough height to install a lift if I wanted (I haven't). I park two cars in it, the other space I use for the lawnmower, snow blower, mountain bikes, trash barrels, compressor, leaf blower, etc.
The garage is pretty loaded with stuff though...my tools, a fridge, work bench, some shelving (which is storing way too much junk). The inside access from house is pretty cool and convenient...it has one entrance right into a hall that leads to the kitchen (few steps going up) and another entrance into the basement (couple steps going down).
I definitely prefer parking in the garage, prevents the cold starts and keeps me from having to scrape ice and snow off the windows!
