My only issue with the 73 is not at all looks related, it is the weight that the bumper adds to the wrong end of the car from a handling perspective. If I had one again , I would gut the bumper and remove the heavy shock mounts, to make it lighter. Looks wise, I love both front ends, the 71-72 style and 73 style. Yes they’re different but I don’t think one’s better looking than the other. I think the 73 front bumper was an excellent look and answer to a tough regulation. I’ve owned several 71 through 73 Stangs, so I know all the differences very well. When we did the conversion of a 72 to a 73 it was because we had a good front clip from a 73 and felt it was just as attractive. I feel the 73 front end was very nicely done, a nice freshen up that was needed to give the old girl one more shot at sales, and doesn’t even look like it’s supposed to be a 5 MPH bumper. I also like the vertical parking lights just as much as the horizontal ones. Basically I love all 71 thru 73’s.
