This very late production DB4 Convertible is finished in its original colours throughout. It is fresh from restoration, where the engine has been uprated to 4.2-litre spec by R.S. Williams, and is accompanied by a very well documented history file, including a history report by noted Aston Martin historian Stephen Archer. This example is 1 of only 70 ever produced, which makes the model the rarest from the David Brown era, even more so than the DB4 GT.
