A friend of mine just purchased a 1973 HQ Kingswood ute with about 160,000kms with two previous owners the original owner had it for about 30+ years, the interior is apparently like new the car is in the current issue of Just Cars, anyhow was chatting to him about it and it has full documentation with it and it came from factory with duel exhaust so I guess this again highlights that things outside the norm were possible if not common place, I am now thinking of putting duel on man Sandman if you were able to order a HQ Kingy with duel why not a Sandman?
