Well, I think I might have just got lucky with a Google search on twin engined propeller aircraft where something looking very similar to the puzzle picture turned up about 23 pages down.
The lady in the tub is actress Barbara Ferris. Being of a certain age, and going to the cinema a reasonable amount in the mid 1960s, I remember she appeared in a film called Catch Us If You Can, also starring the pop group the Dave Clark Five. As far as this puzzle goes, she also appeared in a long-forgotten BBC television series about an airline security agent, played by Nigel Patrick, the programme being called Zero One.
So if I'm right and the aircraft is a Douglas DC5, then discarding the non-numeric characters, zero one plus five gives (non-arithmetically) "015", and my guess is that the car is the Tyrrell 015, built for the 1986 Formula One season.
