His is a roadster, the body made in Australia, but back in 1935 a Plymouth sedan in the United States cost $US510.
Importing the radio from the United States cost $US255 ($NZ307.50). An original chromed lockable petrol cap set him back $US200.
It is worth it to a single man who has a passion for classic American cars - he had an immaculate 1957 Hudson Hornet, along with the Plymouth, at the Oamarican Allcomers Show at the Oamaru Showgrounds on Saturday.
His third car, on display in the Oamaru Car Museum, is a restored 1947 Plymouth Club Coupe.
In addition he has two James motorcycles, a 1954 Cadet and 1953 Captain, both restored.
The Plymouth is a two-door Deluxe Sports Roadster, made by Adelaide motor body builder T. J. Richards, on a sedan platform imported from the United States.
No roadster convertibles were made in the United States and they were unique to Australia.
He bought the car from a friend in Christchurch about six or seven years ago and, apart from having the rims painted red and new tyres fitted, it is pretty much in the condition he got it.
Surrounded by highly polished and immaculate mostly American muscle cars, the Plymouth looked totally out of place.
Technically, it cannot even be driven on the road.
But its scruffy appearance drew the crowds in droves, beating most of the other 80 vehicles on display.
It has rust, holes in the bodywork and trim, part of the interior of the soft top hanging down and an engine that looks so rusty it would never run.
But the 201 cubic inch (3.3 litre) flathead six-cylinder engine, with a three-speed manual gearbox, does run.
Mr McKenzie was going to restore the car, but other car projects got in the way.
Now he is not so sure.
''A lot of people say to me leave it as it is, original,'' he said.
He would like to at least get it legal for the road, repairing the rust holes and other work to have it certified, qualify for a vehicle identification number and pass a warrant of fitness.
