I notice that the Roadster has a plastic shroud under the engine and radiator. This makes access a bit of a pain. Do UK spec cars have the same and would it do any harm to remove this and leave it off ? (12/99)

Do UK spec cars have the same?

Yup.

and would it do any harm to remove this and leave it off ?

Air flow is improved. :-) But exposure to the elements and foreign objects is an issue. Once you get the front of the car lifted it only takes 5 minutes to remove the covers and 10 minutes to refit them. You do like mud and rust in your eyes and nose, don't you? :-) (12/99)
