"It's the only one I know of that's on the road in New Zealand.
"There were only 10,000 made over a period of three years from 1965 to 1967 so there's not many anywhere anymore. I'm very pleased with it."
Mr Spackman's vehicle was one of 48 taking part in the annual Bay of Plenty Vintage Car Club Anniversary Weekend Rally yesterday. He said there was a story behind the car's distinctive design.
"When Rambler were designing this car the designers had it looking more like a Mustang Fastback, sloping right from the windscreen back.
"But Rambler's general manager at the time wanted a back seat that he could sit in with his hat on. And he was quite a tall man. So they had to alter the car's lines to accommodate that."
Mr Spackman has been a member of the BOP Vintage Car Club for more than 20 years and owns two other classic cars, a 1929 Hudson Sedan and a 1922 Hudson Speedster.
Irene Hill, who has been a member of the BOP Vintage Car Club for 10 years, said the day had been a terrific success.
Mrs Hill is organiser of the club's next big event, a rally held over Jazz Festival Weekend, Easter Saturday and Sunday.
Saturday would see a parade of "brass and nickel and old cars", she said. "Chrome came out in 1928, so most of the cars in this parade will be pre-1928. They're real oldies, they're antique cars."
The oldest car of the 28 which took part in last year's event was from 1903.
"We have an open day on the second day, Easter Sunday," said Mrs Hill. The day would be open to pre-1982 cars to attend.
"Because it's called the vintage car club a lot of people don't realise a 1982 car could belong.
"A car has to be 30 years or older.
"We're looking for a 1982 car to be on display so we can say to the young ones, look this is what youre parents were driving you around in."
Anyone interested in entering their vehicle in the parade should contact Mrs Hill on (07) 573 5432.
