I've got the '79 issue, but never will build it. That said, it's a very '60s style model, with some nice parts (SBC, multi-carb intake manifold with multi-piece carbs, nice quick change rearend), but the interior tub is way outdated, the steel wheels have ejector pin marks on the outside faces/lips, and there are some odd details, like the woodgrain firewall.
IMHO, it's worth paying $20 for if you're using it for parts for another 1/16 project (i.e. the Minicraft Model As), or if you want a nostalgic trip down memory lane and aren't concerned with every single detail. The parts fit and engineering of the kit is not as nice as that found on Revell's 1/16 '34 Fords, but I don't see any cause for alarm on any of the parts or assemblies. You may need to really take your time with all the thin, fragile chrome front end related parts, but if you want a unique shelf model, this one'll work just fine.
