Sorry...all too easy to top your sighting.
Check out this photo I snapped:
This was at our annual Palm Beach Cavallino Classic Ferrari festival, which is held each year at the Palm Beach Breakers hotel.
The car is a 1966 Ferrari 250GTO (as mentioned above), now one of only 32. This car was formerly owned by Ralph Lauren, among others. And it was purchased for $21,000,000...the highest price yet paid for a street car (Juan Manuel Fangio's racing car was purchased for $35,000,000).
Also at the same show where I photographed the gorgeous 250GTO were roughly 130 other Ferraris, including 250 Californias, 512s, Testa Rossas, 265GTBs, 365GTBs, and many more, with values of many of the classics ranking in the high single-digit millions.
Living in South Florida, I have to look at $80,000-$270,000 cars every day all over the roads. Rolls Royces, Aston Martins, and Bentleys are like Buicks to the rest of the country, and Mercedes and BMW are like Honda Civics and Ford Focuses around these parts. You want to see the serious iron, come visit my turf!
