When talking reliability, I think the Japanese (Honda, Toyota, Nissan) have the German beat. My 8 years old G35 is still running like a champ with almost 100k miles and a couple of track days. I don’t drive it like a granny either. It often see redline a few times a week.
Unfortunately for me, I’ve been power hungry for awhile. Every new (not brand new but next car) always have more power and better handling and my next one won’t be any different. Because of this, although I’d love to stay with Infiniti, since it has treated me well, I have to go German since Japanese have no real option for me. At least not yet.
