Hi Alan, the idea of the 1/24th scale sports car series was twofold: Establish a category that would gain shelf space in the Auto kit selections with mass merchants.. These were shelves dominated by AMT, MPC, and Revell to some degree. The choice of subjects was totally different and the goal of each kit was to create a model that was easy to assemble... The second goal was a result of the Monogram 1969 Z/28 Camaro. we learned that we did now understand how to model full-fendered contemporary cars. So, the body shapes of the first four subjects were experiments in interpreting body contours and it was done so with two seminars conducted at Monogram Models in our conference room guided by GM Director of Design Chuck Jordan... he was a dedicated model builder and taught our design staff and pattern makers about how to interpret body shapes and contours when the visual point of reference was so different between a full-size auto and a 2X pattern (1/12th scale for 1/24th scale kits). A note of interest... The 450SL was like Bob Reder's 450SL,,,, the Capri II basis was my 1976 blue metallic version.... the Datsun was a natural as was the Porsche 911.... I contacted VW of A and spoke with the late Bill Oursler who worked in PR.. he set us up with a new 924 at Porsche Audi O'Hare and Mike Cook at British Leyland in NJ set us up with the TR-7..... A neighbor's dad found the Chicago Auto Show Light Ivory 924 outside a Chicago are shop several years ago,, it was an early build car and I was able to find a Monogram 924 for him.... still one of the best Porsche shapes ever built!!! The 308 GTB was based upon the fiberglass-bodied 308 owned by GM and maintained by GM Design. No, these kits did not satisfy the experienced builder, but, they "bought shelf space" in K-Mart, Toys-R-Us and smaller chains like Shopko, Rose's and Meijer Thrifty Acres...... Hope this helps.... I hope that Atlantis has these molds.. particularly the 924 and 308 Ferrari
