Here are some quotes from an article by RT Anderson in the Nov. 1972 Pano:

The '72 did not have the same quality as the '66 -- the '66 had more uniform panel gaps that were also "better matched." The tire pressure guage, sun visor mirrors and lug nut socket with teflon inserts was missing from the '72. The trunk "rugs" in the '66 had a better finish and were better fitted than in the '72. The oil dipstick and gauge were not in synch on the '72.

The '72 (an S) was a "much quieter car" and had a "more solid feeling." But that was not necessarily a benefit as "some of the 'man and machine' relationship" was lost.

The handling was greatly imporved, and he attributes that to the front spoiler. He like d the bigger displacement engine a lot more, but doesn't talk much about the "S" cam curve or other engine characteristics.
