Today I was taking a bicicle ride with my brother when suddenly we were passed by a large amount of ferraris and classic alfa romeos. It was an amazing experience hearing and beeing passed by all those fast cars, some of them doing 120+ in that mountain road (for example an F50 was crazy and dangerous).

I searched for some info and It seems to be a "rally", a free run on open roads with the normal traffic. 130 km on 3 rural stages with a final slalom or something like that.

I found some pictures of the past year's edition:

The stratos was there too :)

thats cool, there are lots of rallies like that, like the Supercar Run, limited to either very rare exotics, and once-off cars and concept cars as well as just supercars,
i'd love to see them sometime

Yes, this happened around my area last year,
It was like a rare classic car run or 'point-to-point', it's great to see some old but nice car being used insted of being locked up.

Damn an SS Giulietta, thats crazy
