While I have no issue with the GC, before I bought my Z I had never really looked into getting one. That may be because the 370 just looks so much more sexy then the GC, but I think it also has more to do with my having pretty good luck with Nissan cars, while my previous experiences with Hyundai have been somewhat lackluster. The thought that Hyundai has managed to step up their game with their vehicles is good to know though.
As for interiors, I have noticed that both of the korean automakers are trying to snag some more of the market share by sprucing up their interiors. The new Kia Optima has a neat looking interior, but I can tell you from driving one that they are not nearly as powerful as Kia would like you to believe.
Personally, I wasn't concerned about the interior when I got my Z. The performance was what I was looking for. But I can understand why you would prefer a nicer one. So enjoy the comfy interior Old Man
. Maybe we will see you in the ranks again when the next Z comes out.
Best of luck to you.
