I think the agreed number of the USA GTS models is now 148, although previously it was thought to be 97 or 98.
A casual viewing of the photos appears to be correct for a GTS.
One of the subtle specifics to a GTS is the deck lids were painted in a very light metallic black. Many repaints miss that detail and just use a pure black
I find it strange they did not include a photograph of the pedal box VIN number, as that is the definitive verification for a GTS.
