Porsche fanatics rejoice: An epic collection of Porsche road cars is going to auction, with some of the rarest and most sought-after models to emerge from Stuttgart represented, along with a few other marques that might pic one’s interest. Among the highlights are a delivery-mileage 964 Carrera RS, a yellow Carrera GT, a 911 Carrera 2.7 RS, and a 997 Speedster. The production figures of those range from hundreds to the low thousands, and represent the evolution of Porsche’s iconic sports car. Moving away from Germany you’ll find several Ferraris, a Corvette, and the fastest tank you can buy — the Alvis Sabre. The no reserve auction ends May 16.
