My considerations as to colour ended with the Simca being painted a medium blue (a 50/50 mix of Vallejo 'Light Sea Blue' 71089 and 'Steel Blue' 71087). The wheels were painted 'Golden Yellow' 948 and the hub caps sprayed chrome. The green paint has been reserved for another car currently on its way from Brazil (my first resin kit from Brazil!).
I fitted a suitcase from Plus Models in the car's open trunk. Plus Models have a large selection of good quality detail parts in 1:35. They may be a little pricey, but you don't need many parts to fit out a scene in 1:35.
