Anything Infinti is Nissan dipped in gold. If you like the power and sophistication that comes with Nissan but hate the plastic fantasic interior (please..no offense to Nissan owners...) but the Infinti gives you the interior luxury and the power.

G35 sedan (cuz i like sedans) but its sounds to me like you would prefer the G35 coupe...
Good luck!
