1930: that time at the Mille Miglia Guidotti was together with the great Nuvolari, on the 1750 with compressor; and they arrived first after an exciting sprint which followed a legendary struggle with Varzi, at the average speed, never seen before, of over 100 kilometres per hour.

In the world of motors they still talk about that race for the episode of the switched-off headlamps: let's hear it from Guidotti.

"We had started from behind - says the driver- and Nuvolari was going like hell. Between Bologna and Florence I felt I was on an airplane and thought that we had certainly acquired a good lead. But, at the Florence check they told us we were only level with Varzi, and Campari was one and a half minute behind. When in Ancona we heard that Varzi's time and ours were still the same, we almost went crazy; In Bologna we found out that Varzi had lost ground and we had a four minute lead."

"Nuvolari - continues Guidotti - was exhausted. He gave me the driver's seat: now it was a matter of continuing sensibly, without compromising a win that seemed now certain. In Vicenza they informed us that Varzi had caught up only one minute and ten seconds out of the four minutes he had lost. Nuvolari went back behind the wheel and ran wild: the lead increased to four minutes again - it was already night in Primolano when we saw in front of us the headlamps of another competitor. Initially we thought it was some amateur taking part in the race, then we realized who it was and the final duel began.
