From the 'Official 40th Anniversary 1959-1999' booklet handed out to event participants. Produced by the DeTomaso Factory (black cover, 3/4-rear view of a Pantera GTS on front, photo of a Pantera GTS on the old factory assembly line in Modena. 24 full color pgs).
"Pantera 1970-1990: about 7260 built (includes narrow body GTS, GT-5 and GT5-S plus 'Pantera' 1990-1992 (the factory never used 'si' to describe these last cars) ; about 38 of these built". Note- no factory official totals except for all Panteras lumped together, and even that number is approximate. The last batch of what some call 'Pantera SI' were sufficiently different that the Italian Gov't forced DeTomaso to re-certify it with a crash test. It also has a different Tipo number).
Not in the booklet- three GT5-S cars were factory-converted to Targa type tops. Of the 3 known Targa-Panteras, two were built with Getrag 6-speed transaxles sourced from the Audi RS-2. One is Austrian Franz Krump's 'cirrus-blue' Targa-Pantera; the other is a yellow Targa in Switzerland). A single non-Targa GT5-S was also equipped with a six-speed Getrag. A 3rd Targa-top GT5-S apparently had a std ZF 5-speed.
All the DeTomaso road cars from Vallelunga to Guara are listed in the booklet, together with their spec's and official production numbers. They all start with 'about....' The single exception was the Guara, since at the time of printing of the booklet (cf. text pg 3) in 1993, the Guara was still in occasional production at DeTomaso-Modena, until the following year. Apparently the Pantera (all versions) had ceased production by the time of printing of this factory booklet, but as usual, that's a guess too....
