Manufacture Dates for Panteras

I can fill in some information based on either what I've read, or what I consider to be common knowledge...

Ending date of Standard Panteras prior to GT5? At least 1989, which is well after the GT5 and GT5-S were into production. DeTomaso called all their Euro-Panteras GTS by the post-Ford era, and you could order any flavor of Pantera you wanted, assuming you had the $$. They continued to manufacture GTS, GT5, and GT5-S all simultaneously. The latest GTS I've personally seen was a 1989 model.

GT5 was produced from 1983 on, with #9250 being the first factory produced model. Earlier cars were retrofitted by the factory as well. They were produced until the end (1989 or 1990)

GT5-S was produced from 1985 on. First one built was #9375, actually built in 1984 but sold as a 1985 model. They were also produced until the end (1990)

In 1990, the last "classic style" Pantera, #9562, was built. During the late 80's, a mix of GTS, GT5, and GT5-S were built. Claudia Lodi told me that they produced 39 GT5-S cars in total, discounting the Kirk Evans Amerisport cars. Personally, this number sounds very low to me. I don't think anyone knows the exact mix of cars produced during this era - if the factory doesn't know, then I don't know who would.

The first Si was also built in 1990. A total of 41 were built, 2 were crash tested (although Roland Jaeckel thinks only one was crash tested?) and one was kept by the factory, making 38 sold.

Thank you Charlie for this information. As a supplement, Franz Krump of Austria offers his research: The factory brochure for the 40th anniversary meeting in Modena 1999 said 7260 original Panteras between 1970 and 1990.
First series of chassis was built by Vignale from #1000 to aprox. #7700.
After the Ford connection they started with a second series of chassis in 1976, with #9000 on, made by Maggiora. This series had some quality problems, so they started again with a third series in 1978, with #9100 on, made by Embo. These were the best chassis and Embo made all the chassis until the End of Pantera production.
A white GT5 was first shown to the public at the Turin Motor Show in 1980.
The GT5-S was first shown to the public at the Turin Motor Show in 1984.
This car #9375, pearlwhite with delta wing, later was sold as a 1985 model to Austria. I have owned this car for 10 years, now it is Charlie McCall's car.
All three models, GTS, GT5 and GT5-S were made from the same chassis and were available until 1990.
The last built original Pantera, #9562, was a yellow GT5-S with black interior and without delta wing. This car wears a plaque on the dashboard which says: "the last built original Pantera". It was also sold to Austria in Fall 1990 and should be in Germany now.
The Si Pantera was first shown to the public at the Turin Motor Show in 1990.
These cars were also made by Embo. They have built only 41 cars of this type between 1990 and 1993.
The first two cars #9601 and #9602, a red and a black one were crashtested later this year.
#9603 was the first car, delivered to a costumer in 1991.
The last built car #9641, a red one, was the showcar from the factory museum.
4 of these cars were made as Targa models:
#9636, dark red, 5-speed ZF, still in Switzerland.
#9637, blue, 6-speed Getrag, delivered to Germany, now in Austria.
#9638, gold, 5-speed ZF, delivered to Germany, now in Belgium.
#9639, yellow, 6-speed Getrag, still in France.
Only two 6-speed cars were made ever.
Claudia told me, #9639, built 1993, was the last Pantera sold to a costumer in 1995 by the factory.
I think #9640 is the ADA-Engineering racing Pantera, but it was sold before #9639.
I am not sure about the VIN of this car, but it wears the same new outside rear view mirrors as the Targas from #9636 on.
This car had no luck in Le Mans, but could win the british GT Championship.

Some chassis numbers from the museum:
The last Longchamp, driven by Mrs. De Tomaso is the bordeaux red 1982 Series 2 car, #3277 from the factory museum.
Santiago has driven the red 1973 Series 1 Deauville from the museum, #1118.
