|Aston Martin DB 4 Zagato|
The short version: 3.7 liter, high compression, straight-six making 314 h.p., aluminum body, 100 lbs. lighter than the steel-bodied production car. One way to think about the DB 4 Zagato is as an answer to the Ferrari 250 GT SWB Competizione, even as Ferrari was moving on to the 250 GTO. It's just as beautiful, and in some ways reminiscent of the SWB.
