The earlier matadors had a more conventional front end, but the later ones sure shot out a bit. AMC sponsored one of the bond movies from memory and had the matador in it, and AMC also released a 'Matador Oleg Cassini edition' (after a fashion designer)
A friends grandfather bought the smaller hornet back in 1970 and they still have it, along with the land cruiser he converted to a 350 chev
The problem with the zinc coating is that the zinc oxide layer can be damaged relatively easily (especially with a mower). Hit a small pebble and stuff up the coating and the rust starts.
I just cut up a 30 odd year old shade house that the orchids are in to make way for a bigger one (made of galvanized temporary fencing), and you can see the rust was advanced where it was welded, because you have to take the galv off to get a good weld (and to avoid getting fumigated by zinc).
Then there is hot dip galv or electoplated (effectively electrolosis) - hot dip yields thicker coatings though. Only have limited knowledge of this, and a bit of knowledge is dangerous (as my last go at electrolosis ended up haha)
