From front to back:
In front of the tram a Volkswagen 1300 (Beetle), right of the Beetle a Fiat 131 Mirafiori. Right of the tram some unknown American cars with the exception of the dark red Chevrolet Corvair Mk1. In the middle of the road a Toyota Corolla (KE15 or KE17) coupé. Left of the Corolla, there's a parked Mercedes Benz (type?) and at least two Volkswagen Beetles. Further up the road, downhill there's a yellow Volkswagen Beetle and right of it a parked Volkswagen T1. The white car left of the yellow Beetle looks European, maybe a Fiat 124.
