No I think the ELX didn't get fogs until they changed to Active/Dynamic etc in what 2002ish? The HGT would have had them, and I think there was a HLX spec higher than ELX at one point which had fog lights.
I have seen ELX's both with and without I think, it must have been an option on them maybe or possibly a selling point special offer on some. So don't worry I don't think you've been conned... but I do think Fiat were a bit stingy there all part of why they're cheap I guess!
