Sorry to bump this thread but since I wanted basically this same discussion for Auto x I didn't want to start a completely new topic.
Anyway, I've had a good experience in an s13 Autoxing before and really liked the light, rwd platform (Although, I have to give props to the honda CRX). Now, due to the nature of engine swaps I'm basically in SM with the 200SX (which sounds a lot sexier than it really should be). Anyway, I suppose competing with this car is going to be something new and exciting for me to look forward to and I hope to see some really good times posted by her (especially when it comes to putting some very fast newer models to shame).
One thing I'm sure to miss is the H-stock class I could race in with the CRX (or the G-stock the s13 was in). All of the time, all I had to do was push the car through the course and it would come out on top of its class but now that I"m building for the eventual goal of competing on a track I'm going to find myself in a new world where I'll be a small fish in a bigger sea. It's fun to be making this move and I'm glad I'm doing it in an s12 because I think it's really going to stand out in a crowd of newer vehicles that teenagers are begging their parents for.
