Default C6 g.s. Z16

A local dealer has a '13 G.S. 3LT Convertible 6-speed manual for sale. Two questions. Do all G.S. manuals have dry-sump? Do all '13 G.S. manuals have Z16? I have a '12 G.S. 4LT coupe with non-dry-sump I'd consider trading.

Z16 is the code for GS. And manual coupes GS are dry-sump, hand-assembled LS3s.

only coupes. Convertibles are wet sump, regardless of trans. All autos are wet sump, regardless of body style
