Bigkahuna,
I checked through my references and the only 1962 Pontiac Grand Prix made was the AMT kit of the 1962 vintage. I thought I remembered seeing a resin cast model of the 62 GP but I cannot find it now. If I do find it I'll post it for you. There has been a resurgance of 1950s and 1960s vintage automobiles, for example the Trumpeter 1960 Pontiac, so you may yet see a 1962 Grand Prix. This was the original Grand Prix so one would think it would be a likely subject for a new kit. Keep your fingers crossed. Aloha, rangerj
