The first Testa Rossa hits the market, one of just 17 cars reportedly built in its series

For many enthusiasts who only know Ferrari through the current V8 and V12 road cars or its Formula One cars, the thought of a four-cylinder, two-liter Ferrari must seem like a joke. You must be thinking about a Fiat or an Abarth Fiat, right? But if you examine legendary dual-purpose, street-legal Ferraris, Jaguars, and Maseratis that gentleman sportsmen would drive to the track in the Fifties, the 500 TR was Ferrari's answer. Adding to its legendary status is that the 500 TR was the first Ferrari to be called "Testa Rossa" (literally, "red head") in describing the red finish on its cam covers.

If you're wondering where the "500" nomenclature originates, it refers to the displacement of a single cylinder, just as it did on the three-liter V12s of the era. In the case of the 500 TR, it comes from the Aurelio Lampredi's Tipo 131 motor: a two-liter DOHC (double overhead cam) normally aspirated straight four that produced 180 horsepower at 7,000 rpm using two downdraft Weber 40 DCO/3 carburetors. (In the cars with Gioacchino Columbo-designed V12s, the 250 refers to the single-cylinder displacement of their three-liter engines.) The 500 TR was an evolution of the line of four cylinders derived from that found in the 1953 Formula Two car, as well as a direct descendent of the 500 Mondial of 1954 and 1955.

Tap into your inner James Bond with this DB5 that crosses the block this weekend at Amelia Island

The car cognoscenti will gather in the lush surrounds of Amelia Island this weekend for the annual Amelia Island Concours d'Elegance at the Ritz-Carlton accompanied by a group of auctions that really kicks the Spring car-show season into high gear. We've already covered a one-off 1956 Mercedes-Benz 300 C station wagon that has attracted worldwide attention--and, frankly, we think that vehicle is pretty awesome. But one of the highlights of this weekend's festivities from the Gooding and RM Auction houses is this 1965 Aston Martin DB5 Vantage. If the silhouette looks familiar, that's because it's the updated version of the car made famous by Secret Agent 007 when the vehicle took its star turn in Goldfinger. While James Bond's well-equipped DB5 was finished in Silver Birch (it seems almost every DB5 is now painted that color), this spectacular example is finished in a variation of British Racing Green.
