Best version to buy
2015+ Model Years: Owners strongly recommend the 2015 and later models due to the significant upgrade from a 6-speed to an 8-speed automatic transmission, which addresses the "lazy" shift character noted in the 2014 model. The naturally aspirated V12 engine in these later models is specifically preferred over the newer turbocharged engines found in models like the DB11 for its sound and character.
