I saw a picture in a car magazine many years ago of a two door GT car, with a 6.9 engine. Again, I think this car was built in Switzweland. You would have to be a real detective to find THOSE pictures! I dont I have the keyboard skill to do that!
Here's an easier one:
Not long after joining the Topklasse Website, I posted two pictures of a two door 6.3 coupe. For those that do not remember, I took the pictures myself at the Earl's Court Motorshow in 1970 onto colour slides, and had then scanned into digital format, and posted them onto this site.
Don't know how to find them now, but I think they are interesting. Perhaps someone else may wish to revisit them with a link.
