The 04's+ are nice, but a little too refined for me. I love the pureness of the 00'. I haven't had gearbox troubles or anything. Sure the back is twitchy at times but it takes a lot of skill to drive this car to the max (as an amateur I need 245s at the rear). The car did not pick up as well under 6k, but since I put on a single full-catback (T1R 70mm) it is a lot better in the 3-5k range.
