Here’s where the modern Audi phenomenon began. Based on the DKW F-102, this tidy hemi-headed saloon might not have set the world alight when it was launched, but its solid engineering and neat road manners soon won it lots of friends. If anything it was under-engined and so performance wasn’t exactly sparkling. But the concept was soon expanded once the Audi marque had been successfully re-established. Today few remain, but well worth seeking out if you fancy an inexpensive slice of Teutonic efficiency.
