i sold mine for 10k with alot of mods and low k's so if u look around u will get one for sure.
definately get an s14 over an r33. get the luxury one with the japspec kit and u will be laughing. the interior is so much better than an r33. power wise they can be very fun with simple mods. mine had 180rwk and it was heaps of fun to drive, easy to kick out, and kept up with a few cars.
