Always! Here at work there are 4 MCS, 1 Justa, and 2 Countrymen in our garage on a regular basis. I get here first in the mornings, but usually will find the others parked nearby. I park in the spot up against the stairwell, as it means I can put the passenger side right up near the wall and it gives me enough room to open my door the entire way and still be in my spot. Works great for me knees. Though I've had to leave a few notes on SUV windshields about staying in their own spot, and that I did not park that way so they could steal some of my spot... (none of those have ever parked next to me again either, hmmm). At Target once we had 5 MINIs in a group, it was awesome! 1 of them was a little classic guy. I love those, and man it made the rest of ours look like giants, LOL. Going into a restaurant once after parking next to a hardtop version of my May, the guy that owned her came out as I was at the door, and he gave me a high-five.
At home - every day. My wife has one too. At work - there are about 100 of them in the front parking lot, unfortunately mine is the only one in the back parking lot. Out and about - if there is one near where I plan on parking I'll park next to it
