you'll find it very differnt driving the skyline to the vx. both are decent to drive however the skyline is a smaller car, handels better, faster, and depends on the person looks better.
however it doesn't have cruise control and the fancy trip computers ect.
i have driven my mates vt commodore a fair bit. and its a nice car to drive, just to big for me and i feel more comfortable driving my r33. also i find the commodore has more blind spots and not as easy to feel wats going on.
but end of the day its up to each person
