I GREW UP in a GM family – while our car was a Holden, the die was cast much earlier when my Dad as a young fella bought an early Chev 6. He always had a good word for other GM marques as well, leaving me as a youngster struggling to understand why the GM stable included so many brands – Jaguar-made Jaguars, Ferrari-made Ferraris and MG-made MGs, so what was going on at GM?
