Why do the Mustang II's recieve such a bad reputation?
the bad reputation was the result of outraged mustang fans complaining of the small size and lack of a V8 option in the 74 and 75 models.
They shared some parts with the pinto, but the design and engineering were completely new and the ride quality, handling, and soundproofing were better than previous mustangs. (except for shelbys race proven handling capabilities) One could also argue that the 64 1/2 - 70 mustangs were just restyled falcons, and the 71-73 was just too large and heavy for any real performance with anything less than a big block under the hood.
Opinions about them vary, but they kept the mustang in production until horsepower became popular again in the early 80's
