I don't want to take this thread in another direction, but having a G35 coupe in the family and having spent 5 months in an IS250, the Infinity is more refined and equal in quality, while probably having a few LESS features than the IS. (I've also owned my SC since bought new in 1/02).

I don't believe the future G37'c' will be as refined as the SC, but I'll bet it'll be closer to it than an IS.

Just my 2cents.

 

Not here to argue with you, since we are all Lexus lovers here. Also quality and refinement can be very subjective sometime.

We got 2 Infiniti (01' I30, 05' G35C) and 5 Lexus (See my sigs) in my families, I work on and pay attention to most of them. Maybe I am bias, but in my opinion all Infiniti are less refine with lower quality then their comparible Lexus. My brother in law that own that I30 since new, swear he is not buying another Infiniti again.

The difference when they aged is huge, with similar mileage (~90k miles), our 98' ES300 is way smoother then the 01' I30.
