Seating is comfortable and conforms to a wide range of body types, with power adjustability and ventilation on upscale models. Quality of materials and their fit and finish aren't luxury-level, but they're a tick above the Ford Mustang, which is perhaps the 370Z's most direct competitor on performance and price. Road noise can be high thanks to the large tires and minimal sound insulation, reaching nearly unacceptable levels on some surfaces.
The 370Z's soft-top convertible mechanism saves weight, complexity, and expense, but at the cost of some security and style--a tradeoff some competitors have taken in the other direction. Nissan's path does preserve more trunk space, however.
With relative newcomers to the sporty coupe segment like the Hyundai Genesis Coupe edging in with slightly better interior design and materials, and long-time stalwarts like the Ford Mustang GT gaining yet more power, the 370Z treads a delicate balance that may be due for an update soon.
