Hello
Lots of answers but Keith and Brent were correct on the model airplane, its a Allen Brickhaus designed Scimitar from 1982, I read the original used a Testors 40 (a stock series 21 blackhead) but my brother Karl has a S.T 46 for his. It was designed as a windy weather practice model that would be rugged and simple with fuselage mounted gear . I think the original had a modified Geiseke Nobler foam wing but the plan shows a built up wing.
The car as John and Matt got correct is a Morris Oxford with flat head/side-valve engine and a column change 4 speed. Hard to see in the pictures but it is a much larger car then its much more common relative the Morris Minor and fits 6 people on its bench seats.
Pleasant to drive and very economic but very slow by today's standards, not that it matters much in New Zealand now, as the roads are congested in Auckland and speed limits low and fuel highly taxed, so in many ways it the vehicle for our times ! Added a pic of the inside
