I think the 'Rodger Dodger' was the 1st HW casting to fall victim to the cost-cutting measures of the 'plastic chassis'. It was originally released in 1974 in
full-metal form and dominated living room downhill races everywhere. But when it was re-released in 1977, it had a chromed-plastic chassis and wasn't as heavy or as fast as the original. It continued in plastic form until Mattel finally made it a full-metal version once again in 2006 with an 'HWC' version, and again in 2008 with the "Classics" series.
Anyway, I
affectionately refer to any HW casting that begins its life as a 'metal chassis' car and gets switched to a 'plastic chassis' as a victim of "Rodger Dodger Syndrome".
