It was funny to look at the 92 Mustang 5.0 coupe parked next to me when I picked my kids up from school the other day. My 135 looked bigger than it! I used to own a 93 coupe and that thing felt Iike a much larger car than my BMW does.
I just looked it up and I see what you mean. The largest difference is front shoulder room at about an inch and half more on the 3 series coupe. Every other dimension is more like half an inch and the 1 series actually has more back seat shoulder room than the 3 series coupe. They are much closer in terms of interior size than I thought! Thanks for the info, that's helpful.
