I think so, but I'm comparing them by my memory of about 8 years ago. I chose an SD (82) over the 123 body cars because they felt somewhere between the 123 and say, my 62 Imperial or maybe my 68 New Yorker. Plus, the 126 is still great in parallel parking and emergency evasive maneuvers. I think someone on this forum needs to pass by and give you a carbon purging wild ride in a SD.
