Nissan 370Z Reviews and Owner Comments

Like the car, my first Nissan Roadster after driving BMWs for years. Car is fun to drive and seems solid. Very disappointing that at 450 miles "service engine soon" came on. Dealer says most of these have bad gas caps. Question, why doesn't Nissan replace them on the cars that haven't sold so the customer doesn't have to bring it back immediately after purchase? Starting to wonder what else am I going to find out is wrong after the purchase.
