That's pretty cool! I was a teen in the late 70s and turned my nose up at the smog motor performance cars of the time, it was all musclecars from a decade ago for me, though I did like new SUV's and pickups.
Lately I have been getting more interested in cars of the Malaise era and this summer bought a '78 Magnum GT to keep my Challengers company in my garage.
I talked to Bob Ashton of MCACN about a having a Malaise era muscle car feature in next years show. I have about a dozen car models of the era in mind that should be in the display. Your Roadrunner would be great for it! Let me know if you might be interested in bringing it out to Chicago to have in the show next year and I will keep you informed if this display idea is going to come together!
Anybody else who has a interesting car or truck/factory custom van from that era or knows someone interested let me know also.
