Magazine for nephew

visiting relatives out west this week, I got a 14 year old nephew who expressed a interest in older cars. His dad has zero interest in them. I would like to get him a magazine subscription to keep him interested. What would be a good one for 60's-70's muscle cars for someone that doesn't have a mechanical background? I was looking at Mopar Muscle but it is probably to much for someone that at this point doesn't know what a torsion bar or air gap means. I would like to lean towards Mopars naturally but not lock him out of others if that is how he leans. What would you get?
Thanks
