I had a loaner 3 once when my i4 was in the shop. It was so much narrow than my i4, at least when parking in my tight garage situation it was really noticeable. Only a couple inches I think. A civic is 70.9 inch wide compared to an accord that is 73.3 inches wide. The 3 series is wider than a civic while the 4 series is narrower than an accord, for what it’s worth. The diff between a compact and sub-compact isn’t that great. Edit: it’s actually just an inch narrower. Goes to show how tight my parking situation is.
