All in all I believe the G (Skyline) to be a better looking car than the Z (Fairlady). Actually looking at side profiles of these two cars the G looks more like the 300ZX (90-96). I guess the true difference is that the Z is the 2 seater based on the Z32 platform and the G is the 2+2 based on the Z32 platform. The internals are pretty much the same outside of the interior. As for the convertible, I really think that should have never seen the light of day, maybe a Targa top instead. Just my 2 cents
