My first "real" AMC (had a few Renaults prior to) was an 83 SX/4 Sport 258 5-speed...followed by an 84 wagon, same drivetrain. I can say with all certainty, if you're gonna go long-distance (500+), the wagon is WAY more suited to that type of driving. Tha SX/4 has more of a "sporty" feel to it, and is a little more handy in city driving. If you plan on having more than one passenger, DON'T go with an SX/4!! The rear seat is best folded down for added cargo space....no reasonably sized human is gonna fit back there. That was the reason the guy I bought mine from sold it. His 9 year old daughter wasn't comfortable!! Beyond that, it kinda just runs to your personal opinions on styling etc....
