Supposedly a limited edition 911 Carrera built for the Italian market? Ran across a reference in, of all places, Wikipedia. Any pics?

From Wiki:

"In 1984, Porsche also introduced the M491 option. Officially called the Supersport in the UK, it was commonly known as the "Turbo-look". It was a style that resembled the Porsche 930 Turbo with wide wheel arches and the distinctive "tea tray” tail. It featured the stiffer turbo suspension and the superior turbo braking system as well as the wider turbo wheels. Sales of the Supersport were particularly strong for its first two years in the United States because the desirable 930 was not available.

For the European market in Italy a very exclusive version was introduced by the Porsche agent, ten Carrera model ST (Senza Turbo) were produced to commemorate the myth of the 10th anniversary of the Carrera RS model, revised engine developing 255 bhp (190 kW; 259 PS) they were all "Grand Prix white" with red or blue "Carrera ST" decal on each side of the car and blue or red wheels, the logo carrera ST (and 3.2 on the boot gril) on their famous duck tail, and a special engraved plate on the dash board, the serial N° were 490-499."
