An outstanding example is this surviving showcar from 1967 - On Display at the 1967 Sevilla car show.

..to find the real rare ones amongst the 2000 plus Mustangs and Shelbys at the show.

This one was defintely one of them. A show car sent to the Fiera Seville/Spain back then in 1967 for a car show. Just one of four Shelbys shipped from New York to Barcelona and then on to Seville in May 1967 as the invoice would indicate, in fact the show was earlier in April, so this invoice is probably a customs clearance or charging invoice that was issued later..

As you can take from this invoice, 4 Shelbys - two GT350 and two GT500 were sent to Albina, S.C. in Madrid/Spain and charged to their Banco Iberica in Barcelona, shipped via the ocean from New York. The serial numbers are clearly visible in the invoice making it easy to trace down the others. One of each the GT350 and GT500 was a Competition model, whatever that meant. 

Additonal information:
The current issue of Mustang Monthly features the GT500 from Ted Kitten, no. 1191. Acc. to that article written by Jerry Heasley John Burgess from UK spotted the two GT500s (one Lime Green, one Nightmist blue) in Europe for Bill Collins. The blue one - unrestored - went across the pond to Bill and was subsequently sold to Ted Kitten. 
The blue one being displayed also at a Barcelona fair in 1967 and then delivered to Auto Layetana, sold from there to Jorge Sanuan Pid north of Madrid and a few years later to Fernando Jarado. Our friend Eduardo Torre (with a T-5 used in racing as we reported earlier) ) from the spanish Mustang club bought the car in 1999, later sold it to a collector in the UK, who happened to have the lime green 67 GT500.
