Concept Car of the Week: Alfa Romeo Giulia 1600 Sport (1965)

Autodelta produced 112 Alfa Romeo TZs between 1963 and 1965. The TZ abbreviation – for Tubulare Zagato – refers to the innovative lightweight spaceframe chassis that kept the weight at an impressive 660kg and assured great performance both on the road and on the track. Out of those desirable TZs, Zagato bodied the vast majority but two of the chassis were also handed to rival carrozzerias Bertone and Pininfarina.

One proposed solution to prop up new-car sales in the United States involves paying bonuses to owners of older vehicles who send their cars to the scrapyard and buy new ones. Proponents say that not only does the auto industry benefit, but so does the environment, as emissions decrease and fuel economy typically improves in newer models. Critics, however, say that scrapping older vehicles hurts collectors by reducing the number of older models available and also hurts those least able to afford to buy newer vehicles by driving up the price of used cars.
