Alas, at the moment, objects do not know how to write themselves to a stream. 
A standard format should be created for that.

To solve your problem, create a public method in CCar to write each CCar field 
to the stream :

CCar.class:

PUBLIC SUB WriteTo(hFile AS File)

  WRITE #hFile, Field1
  WRITE #hFile, Field2
  ...
  WRITE #hFile, FieldN

END

But your request is not stupid :-) I add it to the gambas TODO file !
