I've got SALT on and Chrome exterior on my Jan '03 (built late '02 obviously).
The Salt options must have been flexible as my interior is the standard dark metallic grey (which I prefer in my black MINI). The interior lights package includes the footwell lights, a light in the glovebox (if the storage pack is fitted), and also lights either side of the vanity mirrors in the sun-visors.
The chrome exterior is the otherway round I think, there is one large strip on the rear lower bumper, and two small ones either side of the front lower grill.
If it's not got the glovebox (and some don't), then I'd try squeezing the dealer to fit one as part of the deal
Chances are, it'll have been specced by the first owner, I think it's only fifty quid.
