Don't worry, Aston Martin has you covered. 7 speed sequential manual or a 6 speed row your own in their production cars.
6 speed only for the V12.
6 speed SMG or manual for the GT4.
6 speed sequential for the GTE/GT3.
Apparently Aston Martin can afford to keep manuals in their lineup, who'd a thunk it that Porsche couldn't.
