Aston Martin presented at the 2013 Geneva Motor Show the spectacular Aston Martin Bertone Jet 2+2. This one-off build was commissioned by a collector named Barry Weir. The original Aston Martin DB4 GTS Jet 2+3 was launched back in 1968; only 20 were built. The gen 2 was based on the modern Aston Martin Rapide. Though the gen 2 was received so well that Aston Martin considered making a small production run, only one of the gen 2 was built.
