The very last unit of the Alfa Romeo TZ3 by Zagato, a celebratory model of just 10 units designed to celebrate the Italian car maker’s 100th anniversary, is finished and head to the 2013 Amelia Concours d’Elegance next month.

Each TZ3 is one way or another unique. The last one features a “Kamm-tail” design, paying homage to the earlier models, and Zagato’s signature double-bubble roof.

Like the previous cars this TZ3 is based on the Dodge Viper ACR and is powered by the same massive 8.3 liter V10 engine developing over 600 horsepower which enables the lightweight car to go from 0 to 60 mph in 3.5 seconds. Top speed is irrelevant, because this is a limited edition Exotica. Nobody is going risk wiping it off the face of the earth by going too fast!
