Rick-
Everyone knows I love the Firebirds but I give the credit where it's due, and Mustang is a success story, no matter who has built it continuously since mid-year 1964. I remember the Mustang MPG. I still remember the MPG commercial from '75. How sad is that?
I found a rust-free running 4-banger 4-speed MPG and I almost bought it a couple of months ago, just because you don't see them anymore. But I bought a 79 T/A from him instead
The Mustang morphed through the oil embargo early 70's, much as cars are doing right now. It left performance to become more gas-friendly, then began to resurrect itself in 1980. AMC never really changed with times and they paid the price. They either had great innovative cars or laughingstocks, and somewhere after the AMX the innovation disappeared
along with AMC.
