This is some years old but has only had occasional use as my dad always kept his MX5 garaged, but this was just to stop it getting dusty from to-ing and fro-ing.
It fits an NA and NB, I believe it may also fit NC.
It’s a lightweight mesh material as per photos, very light construction.
Available for price of postage (and maybe a small beer! 
) so a tenner or so.
I’ll get it packed and weighed but I doubt it’ll be more than that.
Or available for collection from Aldershot GU12 5AP.
