The 4 speed in that is really a 3 speed with an overdrive 4th gear. It isn't a great performance transmission. I saw the car on Craigslist, I didn't see anything indicating a 'Road Runner Package'. Anyways, the Volare wagon is a great sized wagon. I had a 79 that was my daily driver for years, until someone ran me up over a curb and bent the frame. I still miss that car. I am looking for another but prefer an automatic. I like wagons and they can be made into fun cars to drive. The thing about F-bodies is to look out for frame rot. It is repairable, but will take effort to fix.
If that car was an automatic and the frame was good, I would buy it in a heartbeat.
Not the best pic, but here is one shot of mine...
