if you're looking for a Skyline for the sake of it being new, get the R34 GTt, if you're more inclined to performance, go the R33 GT-R cos at the end of the day you still got the RB26 under the hood.
.......or better yet the R34 GT-R:burnout:
i would go the R33 GT-R VSPEC. i might be the only one saying this...but i prefer the R33 shape to the R34 shape(considering both are GT-Rs). Especially a S2 R33 GT-R VSPEC in midnight purple with white RAYS TE37s:p
