It's a closely fought contest. The 1967 NSU TT TTS brings quicker acceleration, lighter weight, greater rarity to the table, and the 1975 NSU Ro 80 Wankel answers with more power, higher top speed, stronger collectibility. Both are excellent machines that reward their owners in different ways — there's no wrong answer here.
