Looking at the car and pics of the Esprit it seems to me that the door handles ought to be flush with the body?
The 90 Esprit turbo SE that I was considering was the same.NOT FLUSH? The handles were inwards and not flush to the body. Are they supposed to be flush?
There should be two rubber bumpers behind the flap that make them flush ( assuming you are talking about the handle not the surround?) these go missing and are available, replacing them moves the handle flush.
