I had a '97 Mustang Convertable.
And like the 2002
When the top was up... You had a terrible time looking to see what was coming - from the side - when backing up.
But that is true with all rag tops.
Hate to disagree with you but I will. :-)
I own a 2002 Mustang convertible and have no problems backing up with the top up or down. Down does provide a better all around view when backing, but the back window is large enough to see where you’re going.
