I am in the market for this car right now. I know the VQ35DE is a very popular engine. I am a little nervous about buying the 2009 model with the VQ35HR. My main concern in not performance. My main concern is reliability and cost of repairs. I am buying this car an plan on keeping it for the minimum of five years. I want to make sure that after the warranty is up I am not beating myself on the head for picking the wrong model with the wrong engine.
