To be pedantic should the word "replica" feature somewhere.
The car is either
(a) An Aston Martin DB7 rebodied by Zagato in the style of the DB4 GT Zagato. In which case it would be a DB7 Zagato, the fact thatit mirrors the DBA GT is immaterial
or it is
(b) An Aston Martin DB7 rebodied by Evanta in the style of a DB4 GT Zagato. In which case it is a DB 4 GT Zagato Replica by Evanta
But it is not a DB4 GT Zagato
