I'd like to bring this thread back to life, by correcting myself. I wrote (6 years ago) on page 1 that there is one Sport quattro here in my town that was imported from USA, and that I believed that it was one of the original US_spec vehicles. Since then, I have seen the car several times, and I have even seen the VIN number. It turns out that htis car is NOT one of the cars originally sold to USA. It has chassis number 56, and was originally sold to Germany, so it was a US grey market car. It is still owned by the same person who imported it from Florida.
Here's a pic of the actual car, #56
