Dear R.

I have a restored Isabella coupe down here in Florida where I live. I bought the car over from England so it is right-hand drive. My car is not for sale but I will keep my eyes and ears open for you. By the way, i once owned a Triumph Vitesse which is essentially a Herald with 6-cylinder engine. I do not think this car was ever imported into the USA. This was a great little car that suited the small roads back in rural England.
Good luck in hunting down a Borgward.

regards, Steve Burke
