CanAm Prototype or competition prototype? Just a guess, but I am thinking it's one of the early McLaren racers. I doubt it's an SLR as it would say SLR or 722, so I am leaning towards it being an early racecar. Definitley don't think it's an F1.
Yeah i thought it would be one of the 70s cars but then concorso Italiano is generally road cars, and mostly modern era ones at that, so im going to hope its an F1 even if i dont really believe it is! i'll get some pictures of it whatever it is.
