In the last January issue of Autoweek, there was an excellent story of this small restoration shop in Buxted, a small village in Sussex of Great Britain. Their work is fascinating. They have built completely from scratch two Auto union streamliner LSR cars as well as made 30 restorations of of Audi's V16 GP cars. they cast and machine all of the parts in house.
