McCready said the other vehicle involved in the crash was an Audi SUV.
Russell Wilson, a committee member of the American Classic Car Club, said he had seen the Chevrolet at the CRC Speed Show at the ASB Showgrounds before the crash.
"It was beautiful. To see any old classic car with that sort of accident is very, very sad, because they take a lot of time and effort to get to that point, then something happens, and, bang.
"These cars were not designed with modern crumple zones. They are reasonably solid cars but it looks like the front has been pushed towards the rear by a reasonable amount."
