Infiniti G37 Convertible. We at Kelley Blue Book have long been fans of the Infiniti G Sedan and Coupe. Sporty driving dynamics, cool modern exterior design, along with plenty of comfort and technology have made the G one of our favorite sporty entry-luxury models. So when we heard Infiniti would be offering a version of the G37 with a retractable hard-top we were naturally excited. Did the new Infiniti G37 Convertible live up to our expectations?
