The V35's are a different class of car to it's predecessors. They may still share the Skyline name, but where as the previous series skyines were turbo animals with a roaring straight 6, overall the V35 is more refined and more of a larger sports touring cruiser type car. The engine being of larger capacity is torquey and smooth, and the car overall is quite large and solid. IMO they're really nice, but, like I've said they're in a different class compared to the older model Skylines.
It comes down to what you want out of a car, and how much you're willing to spend on it.
