We bought our 2015 GT convertible with an auto because wifey uses it to go to work during the week. Funny part is she now wants a manual. We are trying to decide between a Vette or maybe buying a base GT to send to Shelby. I will say that the paddles are ok for quick downshifting but are rather soggy when going up through the gears. The car in sport mode actually shifts much harder going up by itself.
If you have a choice between the 2 go with the Vette all day long if you have to go Auto... Coming from someone with both there's no comparison.
