Ahh that's a shame, would make restoration more worthwhile, although matching numbers is perhaps not that important if you consider that some markets didn't have the engine number stamped on the ID plate.
Here is a rare French Delivered HLS30.
Facebook changes image URLs around and breaks them later so I copied it here (even though I'd rather just link to it).
Never did get a reply as to what the X values represent around the chassis number.
NB: The engine is just stated as L24 - no numbers...
