Hi Curt and a very warm welcome to our forum.
There aren't many 131s left in this condition regardless of the model, but I have a very soft spot for the 131 S, as Theo will tell you
I have 2 1976 Specials of the type depicted (1600 4-door saloons), one for spares with 19,000 genuine miles.
The other is an immaculate orange one, having one owner (other than me) from new and only 15,000 miles!!
I've owned it since February 2000 and have done very little to it. I had Guy Croft work his magic to the head and it's a fantastic little car now.
(Theo - if you have any photos of NUH perhaps you'd post a couple here please?)
Can't understand why everyone wants a Sport though
