What year was it and did it have the crappy 4 banger or the 170 cu in V6? The V6 in my sister's 77/78 Mustang II wasn't too bad at all. It was a shame to consider most of the Mustang II's (with exception to the Cobra which I thought was cool with the white w/blue striping) as Mustangs, but I still liked them for what they were at the time.
