At the parents house. The W211 only has a few inches of space until the rollers come down. Its very tight lengh-wise. Width-wise not to bad. To prevent the W211 hitting the rear wall, my father and i have a set of wooden planks to act as buffers. They do a tremendous job.
With the parktronic having fits of beeping etc, its can make your heart rush a tad.
At my home, not so much a garage but a drive.
I'm selling up in Dec, so i guess it does not matter too much!
