Remember, this car started out as a 9' 9" (117") wheelbase chassis-only. That is how it rolled out of AC Cars.
There's a good line in the Registry about one of the other "movie chassis" cars, that was built into a Cobra; it states that the proportions of the finished vehicle are so out of whack that they wouldn't even refer to it as a "replica".
I've got about 50 images of 6132...it's a pretty car, but wouldn't pass "accurate-replica-muster" against present day SAI or KMP cars.
